In this article, we explore the anisotropic electron energy loss spectrum (EELS) in monolayer phosphorene based on ab-initio time dependent density functional theory calculations. Similar to black phosphorous, the EELS of undoped monolayer phosphorene is characterized by anisotropic excitonic peaks for energies in vicinity of the bandgap, and by in...

Giant carrier mobility of graphene is significantly reduced due to external perturbations, such as substrate based charge impurities, and their impact can be minimized by encapsulating graphene between hexagonal boron nitride (hBN) layers. Using density functional theory (DFT) based ab initio calculations, we study the static response of such a com...

Based on extensive first principle calculations, we explore the thickness dependent effective di- electric constant and slab polarizability of few layer black phosphorene. We find that the dielectric constant in ultra-thin phosphorene is thickness dependent and it can be further tuned by applying an out of plane electric field. The decreasing diele...

III-V channel materials have emerged as one of the major contenders to replace silicon as the channel material in sub-10nm transistors. Motivated by this, we study the feasibility of using InP as a channel material in extremely scaled MOSFETs. In this work we have performed a comprehensive analysis of the band structure of extremely thin InP channe...

Failure is not an option I Failed thousand times, but i learnt 10,000 times !! "Failure is the first step towards success" is a standout amongst the most heard quotes and is over and over advised to us in every venture of life, yet how frequently do we understand its criticalness or live by its mantra? Sincerely, we don't! We simply anticipate that...

Traditional QWERTY keyboards are large in size and offer little in terms of their ability to modify. A Virtual Keyboard, with slightest physical form may provide an answer to the point of time, where the size of desktops and laptops is becoming smaller, the traditional keyboard acts as a hindrance to further miniaturization. In today’s world many d...

A numerical study has been carried out to understand and highlight the effects of axial wall conduction in a conjugate heat transfer situation involving simultaneously developing laminar flow and heat transfer in a square microchannel with constant flux boundary condition imposed on bottom of the substrate wall. All the remaining walls of the substra...
