Moire-Induced Electronic Reconstruction in van der Waals Heterobilayer PtSe₂/PtTe₂.

ABSTRACT: van der Waals heterostructures composed of a few atomic layers have attracted significant attention in the condensed matter physics community. Although interlayer bonding is weak, effects such as moiré modulation, charge redistribution, and electronic hybridization can substantially modify the band structure and interlayer coupling. In this work, we investigate heterostructures composed of few-layer PtSe₂ and PtTe₂ by using first-principles calculations implemented within density functional theory (DFT) and angle-resolved photoemission spectroscopy (ARPES). While both materials are Dirac semimetals in the bulk form, they undergo a transition to semiconducting states in the few-layer limit. These heterostructures allow systematic examination of how dimensional confinem
