to the electron-hole asymmetry in borophane, its electron-hole conductivity is nearly symmetric. We should mention that at very low temperatures the variation of thermal conductivity will be similar to the charge conductivity $\mathcal{K}\approx (\pi^{2}/3)k_{{\rm B}}T \sigma$ with the Boltzmann constant $k_{{\rm B}}$.

The electrical conductivity of borophane along the zigzag ($\sigma_{yy}$), and armchair ($\sigma_{xx}$), directions versus the chemical potential, in the presence of short-range electro-magnetic scatterers is shown in the figure (\[fig4\]). In this figure $\alpha=0.5$ and $V_{{\vec{k}}- {\vec{k}}'}=V_{0}=1000~e{\rm V}$Å$^{2}$ [@sarma]. The conductivity of graphene is also shown. As can be seen, the overall energy dependence is the same as LR impurity scattering.

Importantly, the anisotropy ratio of the conductivities ($\sigma_{xx}/\sigma_{yy}$), for both LR and SREM scatters has constant values of $7.67$ and $9.27$, respectively that are independent of chemical potential. We compare our numerical results with those obtained for monolayer phosphorene  [@Liuprb16], a highly unique anisotropic 2D material, in the case that $d = 0$, where $d$ is the out-of-plane vertical distance between the charged impurity and monolayer phosphorene. Obtained anisotropic ratio decreases with increasing doping level, varies from 7 to 1.5, depending on the values of $d$ and $n$, the electron (or hole) density. For uniformly distributed impurities
