Transport Properties of Graphene on Strontium Titanate

ORAL

Abstract

We have investigated transport properties of mechanically exfoliated graphene on strontium titanate(STO) in ultra high vacuum at cryogenic temperatures. Field- and temperature-dependent dielectric constant of STO is used to measure the impact of substrate-induced screening on transport properties of graphene.
