From: Defect-gradient-induced Rashba effect in van der Waals PtSe2 layers
a Slab geometry with 10 layers of PtSe2. Blue atoms indicate Pt and the amount of Se vacancy is represented through a color scheme in the right corner of (c). Electronic band structures near M point in the Brillouin zone without (b) and with (c) spin-orbit coupling. Colors in each band indicate the Se/Pt ratio of the Bloch wavefunction.
