  Experimental realization of two-dimensional boron sheets was reported very
recently by Feng et. al. using molecular beam epitaxy on silver (111) surface.
These boron sheets possess promising electronic and transport properties. We
performed the density functional theory (DFT) calculation to see the stability
of two $\beta_{12}$ and $\chi$ polymorphs of boron under strain and further
studied electronic and transport properties. We verified the directional
dependency in electron transport properties in these two boron polymorphs. Here
we report tunable anisotropic transport properties of the borophenes. We also
investigated current-voltage characteristics in low bias regime after applying
strain on these systems to see how this external strain affects the anisotropy
of current.
