K4Hf3Se14
semiconductor· K4Hf3Se14
K4Hf3Se14 is a ternary halide-based semiconductor compound combining potassium, hafnium, and selenium in a layered crystal structure. This material belongs to the family of transition-metal chalcogenides and is primarily of research interest for next-generation optoelectronic and photovoltaic applications, particularly where tunable bandgap or two-dimensional electronic properties are desired. While not yet widely commercialized, compounds in this chemical family are investigated for their potential in solar cells, photodetectors, and quantum devices where traditional semiconductors face limitations.
