Abstract

The electronic-transport properties of single-layer graphene that has a dilute coating of indium adatoms have been investigated. Our studies establish that isolated indium atoms donate electrons to graphene and become a source of charged impurity scattering, affecting the conductivity as well as magnetotransport properties of the pristine graphene. Notably, a positive magnetoresistance is observed over a wide density range after In doping. The low-field magnetoresistance carries signatures of quantum interference effects which are significantly altered by the adatoms.
