The crystal structure and ARPES data of SnSe. a–c The crystal structure of SnSe (a) with a top (b) and side views (c). The black lines indicate the conventional unit cell of SnSe. d A Brillouin zone of the Pnma phase. e A constant energy ARPES intensity map taken at VBM. f Constant energy ARPES intensity maps taken at several different E–EVBM from − 1.4 eV to 0 eV
