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 Introduction to Semiconductor Devices (ELEN E4301) and Theory and Practice of Device Scaling (ELEN E9301, in collaboration with Tom Theis). He is currently teaching the graduate-level course 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.
He is especially interested in emerging materials and devices (especially 2D transition metal dichalcogenides), strain engineering, high-mobility transistors, tunneling transistors (TFETs), and quantum device structures. Past work has included the study of strained Si, strained Ge, strained SiGe, InAs, and GaSb material systems.
In 2018, Teherani received the NSF CAREER Award for his proposal on "Exploiting Many-Particle Physics for Low-Energy Nanoelectronics." He was also awarded 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.
