Schottky barrier heights and band alignments in transition metal dichalcogenides
van der Waals solids actually obey 3D-like Schottky barrier models. 2D and 3D MX2 have similar pinning factors. The metal-MX2 contact does not have van der Waals bonding to the solid. The pinning factor S is small, around 0.10.2 for all MX2.
