Fig. 9From: Electronic Structure and Carrier Mobilities of Arsenene and Antimonene Nanoribbons: A First-Principle Study 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 c–f, the absolute values of deformation potential constant, i.e. the fitted slope, are also markedBack to article page
