Query: Defect-induced conductivity anisotropy in MoS2 monolayers   Various types of defects in MoS2 monolayers and their influence on the
electronic structure and transport properties have been studied using the
Density-Functional based Tight-Binding method in conjunction with the Green's
Function approach. Intrinsic defects in MoS2 monolayers significantly affect
their electronic properties. Even at low concentration they considerably alter
the quantum conductance. While the electron transport is practically isotropic
in pristine MoS2, strong anisotropy is observed in the presence of defects.
Localized mid-gap states are observed in semiconducting MoS2 that do not
contribute to the conductivity but direction-dependent scatter the current, and
that the conductivity is strongly reduced across line defects and selected
grain boundary models.
