Mantu Hudait joined the ECE faculty in September as an associate professor in the microelectronics area. An expert in materials science and microelectronics, Hudait is investigating new materials and device structures for energy-efficient nanoelectronics and alternative energy sources.
He came to Virginia Tech after serving four years as a senior process engineer in the Advanced Transistor and Nanotechnology Group at Intel Corporation. While there, he led a number of R&D programs, with widely recognized, groundbreaking results.
Before joining Intel in 2005, Hudait was a postdoctoral researcher at Ohio State University and served from 1993 to 2000 as a Member of the Technical Research Staff at Bharat Electronics, India.
Hudait’s research at Intel involving heterogeneous integration of III-V transistors on silicon is credited with sparking a move in the field to expand the technology from traditional analog/optoelectronic communication applications to the emerging low-power digital computation and storage applications. His groundbreaking research in the area was recognized by Intel with a Components Research Divisional Recognition Award in 2006 and 2008.
Hudait’s work on heterogeneous integration of indium-gallium-arsenide (InGaAs) quantum well field effect transistors (QWFETs) on silicon is considered a breakthrough in high-speed and ultra-low power transistor research onto Si substrate.
Expanding materials options and energy efficiency
At Virginia Tech, Hudait is continuing research in heterogeneous integration of III-V materials and advanced device structure onto silicon. His goal is to help the technology achieve its promise of expanding the materials options and enable new functionality for energy efficient nanoelectronics.
He is working to establish novel III-V materials and oxide growth capabilities while exploring new device structures, and pursuing innovative integration strategies for incorporation of different semiconductors and device types onto silicon. His research also involves materials innovation to develop new device structures to enhance the conversion efficiency of today’s photovoltaic and thermophotovoltaic cells.
Hudait received his Ph.D. in materials science and engineering from the Indian Institute of Science in 1999, and a master's degree in materials science and engineering from the Indian Institute of Technology in 1992. He has published more than 41 journal articles and more than 45 conference publications. He holds six patents and has 29 patent applications pending.
