Optical Phonon Limited High Field Transport in Layered Materials
Hareesh Chandrasekar, Kolla L. Ganapathi, Shubhadeep Bhattacharjee +2
An optical phonon limited velocity model has been employed to investigate high-field transport in a selection of layered 2D materials for both, low-power logic switches with scaled…
Surface States Engineering of Metal/MoS2 Contacts Using Sulfur Treatment for Reduced Contact Resistance and Variability
Shubhadeep Bhattacharjee, Kolla Lakshmi Ganapathi, Digbijoy N. Nath +1
Variability and lack of control in the nature of contacts between metal/MoS2 interface is a major bottleneck in the realisation of high-performance devices based on layered materia…
Estimation of background carrier concentration in fully depleted GaN films
Hareesh Chandrasekar, Manikant Singh, Srinivasan Raghavan +1
Buffer leakage is an important parasitic loss mechanism in AlGaN/GaN HEMTs and hence various methods are employed to grow semi-insulating buffer layers. Quantification of carrier c…
Growth Stress Induced Tunability of Dielectric Constant in Thin Films
K. V. L. V. Narayanachari, Hareesh Chandrasekar, Amiya Banerjee +4
It is demonstrated here that growth stress has a substantial effect on the dielectric constant of zirconia thin films. The correct combination of parameters - phase, texture and st…
Spotting 2-D Atomic Layers on Aluminum Nitride Thin Films
Hareesh Chandrasekar, Krishna Bharadwaj B, Kranthi Kumar Vaidyuala +4
The availability of large-area substrates imposes an important constraint on the technological and commercial realization of devices made of layered materials. Aluminum nitride fil…
