Short-range defects contribution to the monolayer graphene resistivity

TL;DR

This paper analyzes how short-range defects affect the electrical resistivity of monolayer graphene, emphasizing the role of defect density and its impact on electron scattering.

Contribution

It applies a previously derived electron scattering matrix to describe resistivity dependence on electron density in graphene with short-range defects.

Findings

Large charged defect densities are unlikely in suspended graphene.

Short-range defects significantly influence graphene's resistivity.

The model explains resistivity behavior based on defect characteristics.

Abstract

The derived by us earlier electron scattering matrix for the short-range defects in monolayer graphene is applyed to description of the resistivity electron density dependence. It is argued that large charged defect density is unlikely in the suspended graphene and graphene lying above the trench.
