Direct observation of valley-hybridization and universal symmetry of graphene with mesoscopic conductance fluctuations
Atindra Nath Pal, Vidya Kochat, Arindam Ghosh
In graphene, the valleys represent spin-like quantities and can act as a physical resource in valley-based electronics to novel quantum computation schemes. Here we demonstrate a d…
High contrast imaging and thickness determination of graphene with in-column secondary electron microscopy
Vidya Kochat, Atindra Nath Pal, Sneha E. S. +5
We report a new method for quantitative estimation of graphene layer thicknesses using high contrast imaging of graphene films on insulating substrates with a scanning electron mic…
The Nature of Electronic States in Atomically Thin MoS2 Field-Effect Transistors
Subhamoy Ghatak, Atindra Nath Pal, Arindam Ghosh
We present low temperature electrical transport experiments in five field effect transistor devices consisting of monolayer, bilayer and trilayer MoS2 films, mechanically exfoliate…
