Measuring of electric parameters of graphene in presence of temperature gradient

Abstract

Graphene is one of the most promising materials for application in electronics. It has been recently discovered that on certain substrates graphene is characterized by a rather strong spin-orbit interaction, which is valuable to spintronics applications. In this paper we present an application of a system for measuring of graphene's electrical parameters. The idea of a measuring system originates from the measurements of the pyroelectric coefficient of ferroelectric samples. After a simple modification the system can be used for various experiments related to the determination of electric response of samples exposed to a temperature gradient. Test measurements of monolayer graphene samples and their thermoelectric response are presented.
