GaPS

Gallium phosphide (GaP) is a III-V compound semiconductor ceramic with a direct bandgap, commonly used in optoelectronic and photonic applications where efficient light emission and detection are required. It serves as a foundation material in light-emitting diodes (LEDs), particularly in green and yellow wavelength ranges, and in photovoltaic cells for space and high-efficiency terrestrial applications. Engineers select GaP over alternative semiconductors when wavelength specificity, radiation hardness, or thermal stability in demanding environments becomes critical.
