Ga8 Se8

Ga₈Se₈ is a compound semiconductor composed of gallium and selenium in an 1:1 stoichiometric ratio, belonging to the III–VI semiconductor family. This material is primarily of research and developmental interest rather than established in high-volume production; gallium selenide compounds are investigated for optoelectronic and nonlinear optical applications where their wide bandgap and layered crystal structure offer potential advantages over conventional semiconductors. Engineers consider gallium selenide materials in specialized photonic contexts—particularly tunable optical systems and mid-infrared detection—where their unique electronic and optical properties align with application demands that cannot be met by more mature alternatives like GaAs or InP.
