Zipton Labs LLC will demonstrate the feasibility of avalanche photodiodes made from gallium phosphide grown on silicon virtual substrates. To increase material quality and decrease dark-current noise, gettering will be performed on the substrate and epilayer. The photodetectors will give superior UV quantum efficiencies to that of UV-sensitized silicon photodiodes at a price point much lower than other wider bandgap alternatives.
