· Ge3 As4

Ge3As4 is a III-V compound semiconductor belonging to the arsenide family, composed of germanium and arsenic elements. This material is primarily of research interest for optoelectronic and photonic applications, particularly in infrared detection and sensing systems where its bandgap and carrier properties offer potential advantages over conventional semiconductors. While not yet widely commercialized, Ge3As4 represents an emerging compound in the broader family of germanium-based semiconductors being explored for next-generation detectors, modulators, and integrated photonic devices that require performance in specific spectral windows.
