Scanning tunneling spectroscopy of adsorbates and vacancies on graphene

ORAL

Abstract

Adsorbates and vacancies sensitively influence transport properties of graphene. We have investigated the impact of adsorbates, such as atomic hydrogen and potassium, and vacancy defects on electronic properties of graphene at atomic scale using scanning tunneling microscopy and spectroscopy Our results will be discussed in comparison with previous transport measurements to understand the effect of extrinsic disorder on transport properties of graphene.
