UT Arlington nanopillar fabrication to lead to more efficient electronics

Going verticalA University of Texas at Arlington engineering researcher will build nanoscale pillars that will lead to more energy-efficient transistors in electronic devices and gadgets. Seong Jin Koh, an associate professor in the Materials Science & Engineering Department , has received a $300,000 National Science Foundation grant that could lead to a tenfold reduction in energy consumption of smart phones, laptops and tablets, which could result in an identical reduction in the frequency of battery charging for those devices. “The key is that all

UT Arlington research uses nanotechnology to aid in cooling electrons without external sources

Paper published in Nature CommunicationsA team of researchers has discovered a way to cool electrons to -228 °C without external means and at room temperature, an advancement that could enable electronic devices to function with very little energy. The process involves passing electrons through a quantum well to cool them and keep them from heating. The team details its research in “Energy-filtered cold electron transport at room temperature,” which is published in Nature Communications  on Wednesday, Sept. 10.

UT Arlington engineers working to prevent heat buildup within 3D integrated circuits

In the effort to pile more power atop silicon chips, engineers have developed the equivalent of mini-skyscrapers in three-dimensional integrated circuits and encountered a new challenge: how to manage the heat created within the tiny devices. But a team of UT Arlington researchers funded by the National Science Foundation is working first to minimize the heat generated and then to developing nano-windows that will allow the heat to dissipate before it damages the chip. Ankur Jain, assistant professor of mechanical and aerospace engineering, is working with colleague Dereje Agonafer,

Facebook funds UT Arlington to discover energy efficiencies for computer centers

Facebook has made a multi-year commitment to work with a UT Arlington engineer for a National Science Foundation project related to keeping massive data centers more energy efficient. The Environmental Protection Agency has reported that the energy used in 2006 by the data center industry was 1.5 percent of the total nationwide energy usage. Experts agree that this usage will top 2 percent soon. As such, savings related to data centers’ efficiency could be in the millions for companies with large data centers such as Facebook. UT Arlington’s Dereje Agonafer is part of a cooperative
