James Teherani joined Columbia University in 2015 as an Assistant Professor in Electrical Engineering. He has taught the freshman EE lab for the Art of Engineering (ENGI E1102) and the graduate-level courses Theory and Practice of Device Scaling (ELEN E9301), Introduction to Semiconductor Devices (ELEN E4301), and Semiconductor Device Physics (ELEN E6333).
His research interests span semiconductor materials and semiconductor devices with the goal of explaining device physics through modeling, simulation, and experiment. His group conducts both theoretical and experimental work—from quantum-mechanical simulations to nanofabrication. His research topics include strain engineering, high-mobility transistors, tunneling transistors (TFETs), and electron transport across heterostructures. Past work has included the study of strained Si, strained Ge, strained SiGe, InAs, and GaSb material systems.
Teherani received the NSF CAREER Award in 2018 for his work on "Exploiting Many-Particle Physics for Low-Energy Nanoelectronics." He also received the 2018 Edward and Carole Kim Faculty Involvement Award for excellent teaching and commitment to students. Teherani has also received the 2014 George E. Smith Award for best paper in IEEE Electron Device Letters, the NSF Graduate Research Fellowship (NSF GRFP), and the National Defense Science and Engineering Graduate Fellowship (NDSEG).
He received his PhD and SM in Electrical Engineering and Computer Science from MIT in 2015 and 2010, respectively. His PhD thesis (conducted under Prof. Judy L. Hoyt and Prof. Dimitri A. Antoniadis) studied the fundamental limits of switching abruptness of tunneling transistors (TFETs). He received his BS in Electrical and Computer Engineering from the University of Texas at Austin in 2008.
Prof. Teherani welcomes inquiries from those interested in undergraduate and graduate research opportunities in his group. If interested, please contact him.
