Interband absorption in single layer hexagonal boron nitride
Aniruddha Konar, Raj Jana, Tian Fang +3
Monolayer of hexagonal boron nitride (h-BN), commonly known as "white graphene" is a promising wide bandgap semiconducting material for deep-ultaviolet optoelectronic devices. In t…
Single-Particle Tunneling in Doped Graphene-Insulator-Graphene Junctions
R. M. Feenstra, Debdeep Jena, Gong Gu
The characteristics of tunnel junctions formed between n- and p-doped graphene are investigated theoretically. The single-particle tunnel current that flows between the two-dimensi…
Influence of Metal-Graphene Contact on the Operation and Scalability of Graphene Field-Effect-Transistors
Pei Zhao, Qin Zhang, Debdeep Jena +1
We explore the effects of metal contacts on the operation and scalability of 2D Graphene Field-Effect-Transistors (GFETs) using detailed numerical device simulations based on the n…
Stark-Effect Scattering in Rough Quantum Wells
Raj K. Jana, Debdeep Jena
A scattering mechanism stemming from the Stark-shift of energy levels by electric fields in semiconductor quantum wells is identified. This scattering mechanism feeds off interface…
Thermally-Limited Current Carrying Ability of Graphene Nanoribbons
Albert D. Liao, Justin Z. Wu, Xinran Wang +4
We investigate high-field transport in graphene nanoribbons (GNRs) on SiO2, up to breakdown. The maximum current density is limited by self-heating, but can reach >3 mA/um for GNRs…
Dielectric environment mediated quantum screening of one dimensional electron gas
Aniruddha Konar, Tian Fang, Debdeep Jena
Relaxing the assumption of "infinite and homogenous background" the dielectric response function of one-dimensional (1D) semiconducting nanowires embedded in a dielectric environme…
