Calculated k z dependence of the Fermi surface and band structures of PdTe2 with the spin–orbit coupling and the comparison with the measurements. (a) Fermi surface of PdTe2 measured by using the helium I ARPES. (b1)–(b4) Calculated Fermi surface at kz = 0, 1/3, 2/3, and 1, respectively. The value of k z is in units of π / c . (c) Band structure measured along high symmetry directions in the helium I ARPES experiment. To highlight the measured bands, we show the energy-second-derivative images of the original data. (d1)–(d4) Calculated band structures at kz = 0, 1/3, 2/3, and 1, respectively.
