The Pt deposition leads to the Fermi level shift (FLS) for the pristine WSe 2 as well as for the ATM films, where the FLSs of Pt/WSe 2 and Pt/ATM are similar of about 0.3 eV. This actually proves that an additional deposition of the Pt on top of the semiconductors improves the charge transfer to the electrolyte decreasing the barrier at the SEI. Hence, this metal-semiconductor Schottky barrier at the ATM/WSe 2 heterojunction is an additional benchmark.
