Tunable, multifunctional opto-electrical response in multilayer FePS₃/single-layer MoS₂ van der Waals p-n heterojunctions.

ABSTRACT: The combination of specific van der Waals semiconductors in vertical stacks leads to atomically sharp heterointerfaces with unique properties, offering versatility and additional functionality for thin, flexible, optoelectronic devices. In this work, we demonstrate heterostructures built from single-layer MoS₂ (n-type) and multilayer FePS₃ (p-type) as multifunctional p-n junctions where robust photoluminescent light emission and broadband electrical photo-response coexist. This is made possible by the inherent properties of the materials involved and the precise energy band alignment at their interface, which preserves the photoluminescent emission provided by the single-layer MoS₂ and confers exceptional tunability to the system. Indeed, through small chan
