in the vicinity of the charge neutrality point. In comparison to phosphorene, a highly unique anisotropic 2D material, borophane with a higher anisotropy ratio ($\sigma_{xx}/\sigma_{yy}\sim10$), is an unprecedented anisotropic material. This high anisotropy ratio together with the large figure of merit, suggest that borophane is promising for the thermoelectric applications and transport switching in the Dirac transport channels.'

Introduction {#sec:intro}
============

Over the past decades, boron, the left neighbor of carbon in the periodic table, has been expected to form various boron nanostructures, such as zero-dimensional all-boron fullerene-like cage cluster $B_{40}$ [@mannix2015synthesis; @Gonzalez2007prl; @Gonzalez2007nrl], 1D boron nanowires and nanotubes [@Otten2002; @F.Liu-nanowire; @Ciuparu2004; @F.Liu2010], double-ring tubular structures [@Kiran2005; @Oger2007; @An2006] and 3D superhard boron phases [@Eremets2001], at the past decade. Among these mono-elemental structures graphene-like 2D structure of boron, known as borophene has attracted considerable attention both theoretically and experimentally, due to its exceptional properties and promising applications in nanoelectronics [@H.Liu13; @X.Wu12; @Y.Liu13; @Z.Zhang15].

Theoretical investigations indicate that due to the electrons in Fermi surface arising from the hybridized states of the $\sigma$ and $\pi$ bonds, 2D boron structure may be a pure single-element intrinsic superconducting material with the highest
