Engineering and Probing graphene-based 1D channels

ORAL

Abstract

Interaction effects might play an important role in transport properties of a clean ballistic 1D channel. The study of electronic properties of confined electrons in 1D nanostructures is a less explored area in layered materials research mostly due to technical difficulties related to disorder and lack of control on the confinement potentials. In this talk I will describe techniques to achieve electrostatic control over sub-50nm length scales with contaminant free interfaces thus creating clean and tunable nano constrictions in vdW heterostructures. I will also discuss transport measurements of these narrow channels both at zero and high magnetic fields where the interplay between confinement and interaction effects can lead to novel transport regimes.
