· PSe

PSe is a layered semiconductor compound combining phosphorus and selenium, belonging to the family of two-dimensional (2D) materials and van der Waals crystals. This material is primarily of research and developmental interest rather than established in high-volume industrial production, with potential applications in next-generation optoelectronic and electronic devices. Engineers consider PSe for applications requiring thin-film semiconductors with tunable band gaps, particularly in contexts where the layered crystal structure enables mechanical exfoliation and integration into flexible or heterostructured devices.
