(color online) Band structures of electron-doped arsenenes at four doping levels: (a) 0.1 e/cell, (b) 0.2 e/cell, (c) 0.3 e/cell, and (d) 0.4 e/cell. The Fermi energy is set to zero. The solid blue lines represent the band structures obtained by first-principles DFT calculations. The red circles denote the band structures obtained by interpolation with MLWFs. (e)–(h) Fermi surfaces correspond to the band structures shown in panels (a)–(d), respectively.
