Ge2 Se4
semiconductor· Ge2 Se4
Ge₂Se₄ is a binary chalcogenide semiconductor compound belonging to the germanium-selenium family, which exhibits glass-forming and crystalline phases depending on composition and processing conditions. This material is primarily investigated in research contexts for infrared optics, phase-change memory applications, and as a component in chalcogenide glass systems; its notable attributes include transparency in the mid-to-far infrared spectrum and potential for nonlinear optical devices, making it of interest where conventional semiconductors fall short in the IR region.
