Intrinsic Fermi Level Pinning and Reversible Depinning at Ultralow-Defect Epitaxial MoSe2/Au(111) Interfaces
Fermi level pinning (FLP) fundamentally limits contact engineering in two-dimensional semiconductors, yet its intrinsic origin remains obscured by the presence of interfacial disorder and defect-induced gap states. Although theoretical models attribute FLP to metal-induced gap states (MIGSs) and interface dipoles, dire...
