Fig. 4: Band dispersions along the kz direction taken in the I and C-CDW phases.
From: Band insulator to Mott insulator transition in 1T-TaS2

a kz dependence of the band positions in the I phase at 225 K. kz is calculated using the inner potential V0 = 17.5 eV. b Photon energy dependence of EDCs taken at Γ at 225 K. c and d are the same as a and b but taken in the C-CDW phase at 160 K. Red and blue circles are the fitted band positions. Error bars are estimated from peak fittings and defined as s.d.
