From: Probing and manipulating the Mexican hat-shaped valence band of In2Se3
a The Brillouin zones (BZ) of 1 T, 2H and 3 R β-In2Se3. b Calculated colour plot of energy (in eV) versus in-plane k-vector for the valence band of bulk 1 T, 2H and 3 R β-In2Se3 for kz at Γand at the edge of the BZ. The zero energy corresponds to the valence band maximum. c Calculated colour plot of energy (in eV) versus in-plane k-vector of the conduction band of bulk 1 T, 2H and 3 R β-In2Se3. The zero energy corresponds to the conduction band minimum. The projected in-plane hexagonal BZ is overlayed on the plots in parts (b) and (c).
