Abhinandan BorahBorah came to Columbia to work with Professor James Teherani in 2016. After earning his BTech in electronics and communication engineering from National Institute of Technology Silchar in 2013, he worked at IBM India as an associate systems engineer. In 2014, he joined Tata Institute of Fundamental Research (TIFR), Mumbai, as a junior research fellow through the Department of Science and Technology, India. At TIFR, he worked on experimental studies of 2D materials for applications in electronics and nanoelectromechanics.
At Columbia, Borah conducts both experimental and theoretical work on 2D semiconductor materials and devices. His current research in the Teherani group focuses on van der Waals heterostructures. These structures of multiple 2D materials stacked atop one another are named for the weak van der Waals out-of- plane bonding exhibited by 2D materials. Made from a wide selection of atomically thin materials, they have demonstrated exciting physics and promising results for electronic and optoelectronic applications. |
Ankur NipaneAnkur joined Columbia University as a PhD student in Electrical Engineering in 2016. He received his B. Tech. degree in Electronics and Communication Engineering from Visveswaraya National Institute of Technology, Nagpur in 2011, and M. Tech. degree in Electrical Engineering with specialization in Microelectronics from Indian Institute of Technology, Bombay (IIT-Bombay) in 2015. At IIT-Bombay, he worked on selective area doping of 2D materials for enabling high performance 2D-FETs for which he received “Best Master’s Thesis” award. Later, he joined Taiwan Semiconductor Manufacturing Company (TSMC) as process integration engineer where he worked on yield improvement of high-voltage devices. He was awarded the Columbia SEAS Presidential Distinguished Fellowship in 2016. His current research involves theoretical and experimental study of metal contacts to 2D materials.

Marco FratusMarco was a former research scholar in the Department of Electrical Engineering at Columbia University. He received his BS degree in Biomedical Engineering from Politecnico di Milano in July 2014 with a thesis work focused on electronics layout optimization for the control system of a neuronal chamber. As part of his master studies, he is involved a Double Degree program between the Electronics Engineering department at Politecnico di Milano and ICT department at KTH, Sweden. Regarding his interests for nanoelectronics and nanotechnology, he has always been excited by novel FET devices and how “More than Moore” architectures can be exploited for biological applications.
His research in Teherani’s group focuses on the theoretical modeling of scattering mechanisms in a saturable absorption condition for graphene monolayer radiated by few THz sources at very low temperature. Marco is now a PhD student in electrical engineering at Purdue University. |
Dr. Younghun JungYounghun is now an engineer at Samsung Electronics in Korea.
