Band structure and band gap of 1T’ WSe2. a,Brillouin zones of 1T’ WSe2 with three domains separated by 120°. b Calculated band structure of 1T’ WSe2. c Detailed band structure along \(\overline {{\mathrm{\Gamma Y}}}\) with the indirect gap Eg labeled. The Se 4p and W 5d weights for the two topmost bands near the zone center are indicated by the red and blue dot sizes, respectively. d Two ARPES maps taken along \(\overline {{\mathrm{\Gamma Y}}}\) and \(\overline {{\mathrm{\Gamma X}}}\) with the sample at 10 K. The overlaid red and cyan curves are computed bands for the mixed-domain configurations. The experimental Eg is indicated
