The detector is eight to nine orders of magnitude –100 million to as high as 1 billion — times faster than the existing technology, and a Texas A&amp;M University at Galveston professor is a key player in the discovery.</p> <div id="attachment_21969" class="wp-caption alignright"> <p class="wp-caption-text">Luke Nyakiti, assistant professor in marine engineering technology and Materials Science and Engineering at Texas A&amp;M University at Galveston, is part of the research team that has had its work published in the current issue of <em>Nature Nanotechnology.</em> Nyakiti also has a joint appointment in the Department of Materials Science &amp; Engineering at Texas A&amp;M University.<em><br /></em></p> </div> <p>Nyakiti and colleagues from the University of Maryland, the University of Massachusetts, the U.S. Naval Research Laboratory and Monash University in Australia fabricated the tiny photothermoelectric detector following successful growth of graphene at the Naval Research Laboratory in Washington, D.C. The project was funded by the office of Naval Research and the National Science Foundation.</p> <p>The team’s goal was to utilize the exceptional electronic carrier properties of graphene to create a photo detector device that could detect radiation at room temperature with the fastest response, which previously has been extremely difficult to do. The researchers used a two-dimensional material called graphene that is made of carbon atoms that are arranged in a honeycomb-like geometrical structure (the diameter of a human hair is 300,000 times thicker than a two-dimensional sheet of graphene).</p> <p>Graphene was chosen because it conducts electricity with ease, it is nearly transparent, and it is remarkably strong (100 times stronger than steel).  Also, it is very sensitive to energy absorbance.</p> <div id="attachment_21970" class="wp-caption alignleft"> <p class="wp-caption-text">“The problem before is that there has always been a ‘slow response’ when it came to detecting radiation in the terahertz frequency range, especially at room temperature, and the technology that currently exists operated at very cold temperatures, subsequently requiring  supportive electronic systems that adds to the cost,” Nyakiti explains.</p> </div> <p>He says the benefit of using this detector is that its signals do not pose a health hazard to the people using it. Also, besides the extremely high sensing speeds reported by the device, the team anticipates further improvements in sensing ability.</p> <p>“We are very excited that our detector system provides a unique answer to fast, subtle detection capabilities that are a million to a billion times faster in its detection capability, without posing short-term or long term health hazards to those who are operating it,” Nyakiti  reports .</p> <p>“It was indeed an exciting time for all of us when this happened.  Because it is much more effective in detecting radiation, the device could be very promising for homeland security purposes.  It also might have applications in mobile devices, medical imaging and other uses.</p> <p>“This has the potential to open up other device possibilities in medical applications. This is a huge first step.”</p> http://engineering.tamu.edu/news/2014/09/15/texas-am-professor-helps-to-develop-new-device-that-detects-radiation-better http://engineering.tamu.edu/news/2014/09/15/texas-am-professor-helps-to-develop-new-device-that-detects-radiation-better Mon, 15 Sep 2014 00:00:00 CST Liang's research featured on Popular Mechanics Hemali Tanna <hemalitanna@tamu.edu> http://engineering.tamu.edu/news/2014/09/12/liangs-research-featured-on-popular-mechanics <p><a href="/mechanical/people/liang-hong">Dr. Hong Liang</a>'s research on how gold nanoparticles can destroy superbacteria in the human body such as <span><em>Escheria coli</em> and drug-resistant </span><em>Staphococcus aureus </em>was featured on <a href="http://www.popularmechanics.com/science/health/life-extension/to-kill-superbacteria-bring-on-the-bling-16988989">Popular Mechanics</a>.

Apparently, six names were proposed for the revolutionary device discovered in 1947 by William Shockley, John Bardeen, and Walter Brattain. The winning moniker was “transconductance varistor,” mercifully shortened to “transistor.” (Click here for a fascinating, full history of transistors.) A varistor, as you know, is an electrical resistor whose resistance is a function of applied voltage, thanks to its nonlinear current–voltage characteristics. Varistors are used as surge protectors (pdf) and made of zinc oxide tuned with bismuth, manganese, or cobalt additives.</p> <p>So a new paper published out of Texas State University on novel “varistor embedded ceramic transistors” seems at first glance to have a paradoxical circularity. ACerS Fellow and lead author R. Kumar Pandey, professor emeritus in the Department of Electrical and Computer Engineering at Texas A&amp;M University, explains in an email that his group’s work “demonstrates that varistors and transistors are inherently coupled devices. These hybrid devices can simultaneously be used in the same electronic circuit as a varistor to protect the circuit elements against overshoot of prescribed voltage supply and as a transistor for signal amplification and electronic switch.”</p> <p>The investigation began humbly. Pandey took a position in 2007 at TSU after retiring from his 30-year academic career at Texas A&amp;M and University of Alabama at Tuscaloosa. His task was to build an electrical engineering program and to mentor young faculty. With that accomplished, Pandey looked for ways to “involve undergraduate students in research and independent thinking,” he says in an email. He was teaching a course on electroceramics, and “We had to begin somewhere and it had to be simple and low budget research. Electroceramics research provided the ideal situation,” he says.</p> <p>They worked with a solid solution of 55 at% FeTiO3 (ilmenite) and 45 at% Fe2O3 (hematite), which they abbreviate as IHC45. The material is magnetic, has a wide bandgap, and its p-type semiconductivity is stable through 700°C.<br />Pandey knew from previous work that current could be amplified by applying a two terminal varistor with a bias voltage. As Pandey analyzed the data the undergraduates generated, he wondered what contribution the biasing voltage made on the current­–voltage characteristics of the varistor. Pandey suspected the data indicated a transistor embedded in the biased varistor, and he took it to Stapelton for a second opinion. Stapelton recalls that day, saying in an email, “I told him that [the I–V graph] looked like a transistor curve, and then he showed me the device. To say that it caught my interest is mild.”</p> <p>They set up a series of experiments to confirm the results and found that three types of embedded transistors form in response to external applied fields: bias-voltage-tuned transistor (VBT), electric-field-tuned transistor (E-FET), and magnetic-field-induced transistor (H-FET). The paper, “Properties and applications of varistor–transistor hybrid devices” goes into detail regarding the I–V characteristics for each configuration. The graphs shows the I-V curve (transistor current vs. voltage) response of manganese-doped pseudobrookite under different applied bias voltages.</p> <p>In the paper, Pandey et al. suggest possible uses for such devices: voltage-controlled current source, low pass filter (VBT); current-controlled voltage source, low pass filter (E–FET); precise current detector, signal amplifier, and magnetic field sensor (H–FET). They would find application in consumer electronics, defense electronics, radiation hard electronics (for space), high-temperature electronics, handheld device electronics, and bioelectronics.</p> <p>If the authors are right about the potential usefulness of these devices, they will need to be manufactured in very high volumes. Pandey and Stapelton think that films of these of hybrid devices could be made by photolithography or pulsed laser deposition—processes that already exist for industrial-scale manufacture. Larger devices would require working on improving microstructures, for example, by hot processing, according to Pandey.</p> <p>Interestingly, this work seems to address one of the eight grand challenges of ceramic science identified by a 2012 NSF workshop—controlling properties of oxide electronics. The open access JACerS article reporting the workshop conclusions states: “Major scientific advances are required, including a sophisticated ability to control stoichiometry, strain, defect chemistry, crystallinity, and diffusion at interfaces, which incorporate increasing chemical, structural, polar, and bonding contrast. By nature of their complex structure and chemistry, active interfaces in oxide ceramics create a rich diversity of future technologies, but scientific advances will require comprehensive efforts that integrate theory with experiment.”<br />Pandey reaches much the same conclusion, saying, “Another important materials problem to solve would be to find suitable dopants leading to high values of carrier motilities necessary for high speed transistors. Oxide semiconductors usually have low motilities, which is a drawback from the device point of view.”</p> <p>Stapelton neatly provides perspective in an email, saying, “What we have built so far is roughly analogous to the first hand-made silicon transistors. It is enough to prove that the technology works but is several generations from being a mature technology.”<br />While the researchers get to work on the chemistries, processing, and characterization, the etymologists can start working on a name for these new devices.</p> <p>The paper is “Properties and applications of varistor–transistor hybrid devices,” published in the Journal of Electronic Materials (DOI: 10.1007/s11664-014-3067-8). The group just published a follow-up paper in Ceramic Transactions Vol. 249, “Configurations, characterizations and applications of novel varistor–transistor hybrid devices using pseudobrookite oxide semiconductor ceramic substrates.”</p> http://engineering.tamu.edu/news/2014/09/12/ece-professor-emeritus-discovers-‘varistor-embedded-ceramic-transistor-hybrid-devices http://engineering.tamu.edu/news/2014/09/12/ece-professor-emeritus-discovers-‘varistor-embedded-ceramic-transistor-hybrid-devices Fri, 12 Sep 2014 00:00:00 CST Mechanical behavior of twinned aluminum revealed by researchers led by Zhang Hemali Tanna <hemalitanna@tamu.edu> http://engineering.tamu.edu/news/2014/09/12/mechanical-behavior-of-twinned-aluminum-is-revealed-by-researchers-led-by-zhang <p>A <a href="https://sites.google.com/site/xzhanggroup/">research group</a> led by <a href="/mechanical/people/zhang-xinghang">Dr. Xinghang Zhang</a>, associate professor and the Gulf Oil/Thomas A.

To kick off the semester, CSE had several orientation activities for the incoming students such as a formal Graduate Student Orientation and the inaugural Graduate Student Boot Camp.</p> <p>The Computer Science and Engineering Graduate Student Association (CSEGSA) Mentoring Program hosted its inaugural Graduate Student Boot Camp, which was the kick-off event for the student organization. It was held Aug. 30, in the Harvey R. “Bum” Bright building. The event focused on presenting a sense of welcome and community to incoming students. During the boot camp, CSEGSA covered three main areas of information from the student perspective to make the transition to America and graduate school easier. These topics included life in Aggieland and education in America, research in graduate school and TA/Mentor training. CSEGSA also provided lunch and community building activities during the boot camp to add a bit of fun to the program. The boot camp was a huge success for its debut. If you are interested becoming a part of CSEGSA, it meets weekly on Mondays from 11 a.m. to noon in HRBB 310A.</p> <p>On Sept. 1 and Sept. 3, the Department of Computer Science and Engineering held the Graduate Student Orientation, which was mandatory for all new incoming fall 2014 graduate students. On the first day each of the supervisors for the various groups in the CSE department introduce its staff and the various duties performed. Some student organizations also made short presentations. On the second day there was a student panel and faculty panel that answered questions from the students. After the panels, there was a poster presentation by various current graduate students detailing their research.</p> <p>“The success of the boot camp far exceeded our expectations,” said Stephanie Valentine, <span>Vice President of Mentoring Activities.</span> “One of our biggest goals for the event was to build a cohort among the new students. The community of grad students in our department needs strengthening, and I think the boot camp was a huge step in the right direction. At one point, there were 70 computer scientists in a room together talking and taking selfies. It was a beautiful sight.”</p> <p>CSE is excited about the Graduate Program and looks forward to another great year with new and returning students.</p> <p> </p> <p> </p> http://engineering.tamu.edu/news/2014/09/11/cse-graduate-student-boot-camp-and-orientation http://engineering.tamu.edu/news/2014/09/11/cse-graduate-student-boot-camp-and-orientation Thu, 11 Sep 2014 00:00:00 CST Dr. Tiffani Williams advances women in computing Rachel Rose <rdaggie@tamu.edu> http://engineering.tamu.edu/news/2014/09/11/dr-tiffani-williams-advances-women-in-computing <p><img width="210" height="270" src="/media/554542/image-of-tiffani-williams.jpg" alt="Image of Tiffani Williams" class="leftalign"/>Dr. Tiffani L.
