Abstract
The main goal of our study was investigation of the influence of the deformations (sufficiently large for the establishing the non-zero gap) on electrotransport properties of impure graphene. To achieve this purpose, we implemented the simulation package that allows to perform numerical calculation of the conductivity and mobility of graphene samples subjected to two types of the uniaxial strain: along zigzag and armchair edges. All numerical calculations are performed within the Kubo-Greenwood methodology along with a tight-binding model. Transport properties are studied in case of a presence of impurity atoms described by the weak short-range scattering potential. Various deformation values are considered. The uniaxial strain acts as an additional source of the electron scattering, herewith, can strongly affect both mobility and conductivity of graphene and introduce anisotropy of its electron transport properties.
