· JVASP-5809· MgPSe3

MgPSe3 is a layered ceramic compound belonging to the metal phosphorus chalcogenide family, characterized by a two-dimensional crystal structure with weak van der Waals interlayer bonding. This material is primarily of research interest for next-generation electronic and optoelectronic devices, where its layered geometry and tunable band structure make it attractive for applications requiring thin-film semiconductors, heterostructure engineering, and exfoliation into nanosheets. Unlike conventional bulk ceramics, MgPSe3 represents an emerging class of materials being explored for flexible electronics, photodetectors, and other quantum-scale device concepts where layer-by-layer engineering provides design flexibility.
