· ZnGeP2

ZnGeP₂ is a II-IV-V₂ compound semiconductor with a direct bandgap, belonging to the chalcopyrite crystal family. It is primarily used in nonlinear optical and infrared photonic applications, where its combination of wide transparency window and strong nonlinear optical coefficients makes it valuable for frequency conversion and mid-infrared laser systems. The material is notably harder and more chemically stable than alternative infrared crystals like CdGeAs₂, making it preferred for demanding optical environments, though it remains more specialized and less mature than conventional semiconductors like GaAs.
