Photoresponse of atomically thin MoS2 layers and their planar heterojunctions
Sangeeth Kallatt, Govindarao Umesh, Navakanta Bhat +1
MoS2 monolayers exhibit excellent light absorption and large thermoelectric power, which are, however, accompanied with very strong exciton binding energy - resulting in complex ph…
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…
Underlap Optimization in HFinFET in Presence of Interface Traps
Kausik Majumdar, Rajaram S. Konjady, Raj Tejas S. +1
In this work, using 3D device simulation, we perform an extensive gate to source/drain underlap optimization for the recently proposed hybrid transistor, HFinFET, to show that the…
High On-Off Ratio Bilayer Graphene Complementary Field Effect Transistors
Kausik Majumdar, Kota V. R. M. Murali, Navakanta Bhat +2
In this paper, we propose a novel S/D engineering for dual-gated Bilayer Graphene (BLG) Field Effect Transistor (FET) using doped semiconductors (with a bandgap) as source and drai…
External Bias Dependent Direct To Indirect Bandgap Transition in Graphene Nanoribbon
Kausik Majumdar, Kota V. R. M. Murali, Navakanta Bhat +1
In this work, using self-consistent tight-binding calculations, for the first time, we show that a direct to indirect bandgap transition is possible in an armchair graphene nanorib…
Effects of Parasitics and Interface Traps On Ballistic Nanowire FET In The Ultimate Quantum Capacitance Limit
Kausik Majumdar, Navakanta Bhat, Prashant Majhi +1
In this paper, we focus on the performance of a nanowire Field Effect Transistor (FET) in the Ultimate Quantum Capacitance Limit (UQCL) (where only one subband is occupied) in the…
