a The used rectangular supercell for 2D mobility calculations, in which the x and y directions corresponds to the zigzag and armchair orientations of sheet, respectively. b The corresponding PBE band structure of As sheet, where band edges for the heavy/light hole (h/l) and electron (e) are marked. c, d The variations of total energies, absolute energies of VBM and CBM of As nanosheet versus x and y directional strains. e, f Similar to c, d, but the data is adopted to the Sb case. In cf, the absolute values of deformation potential constant, i.e. the fitted slope, are also marked
