Raman and Photoluminescence Study of Dielectric and Thermal Effects on Atomically Thin MoS2
Rusen Yan, Simone Bertolazzi, Jacopo Brivio +7
Atomically thin two-dimensional molybdenum disulfide (MoS2) sheets have attracted much attention due to their potential for future electronic applications. They not only present th…
Unique prospects of graphene-based THz modulators
Berardi Sensale-Rodriguez, Tian Fang, Rusen Yan +5
The modulation depth of 2-D electron gas (2DEG) based THz modulators using AlGaAs/GaAs heterostructures with metal gates is inherently limited to < 30%. The metal gate not only att…
Effect of optical phonon scattering on the performance of GaN transistors
Debdeep Jena, Siddharth Rajan
A model based on optical phonon scattering is developed to explain peculiarities in the current drive, transconductance, and high speed behavior of short gate length GaN transistor…
High field transport in graphene
Tian Fang, Aniruddha Konar, Huili Xing +1
In this work, high field carrier transport in two dimensional (2D) graphene is investigated. Analytical models are applied to estimate the saturation currents in graphene, based on…
Effect of high-K dielectrics on charge transport in graphene
Aniruddha Konar, Tian Fang, Debdeep Jena
The effect of various dielectrics on charge mobility in single layer graphene is investigated. By calculating the remote optical phonon scattering arising from the polar substrates…
Mobility in Semiconducting Graphene Nanoribbons: Phonon, Impurity, and Edge Roughness Scattering
Tian Fang, Aniruddha Konar, Huili Xing +1
The transport properties of carriers in semiconducting graphene nanoribbons are studied by comparing the effects of phonon, impurity, and line-edge roughness scattering. It is foun…
