Used in optoelectronic devices due to its semiconducting properties, particularly in infrared optics and nonlinear optical applications. It serves as a key material in frequency conversion processes like second-harmonic generation, making it valuable in laser systems operating in the mid-infrared range. Also investigated for use in photovoltaic cells and thin-film solar technologies owing to its favorable bandgap and light absorption characteristics. Its layered crystal structure supports applications in flexible electronics and two-dimensional material research.
