摘要
InGaN/AlGaN light emitting diode structures (LED) grown epitaxially on sapphire substrates were on-wafer characterised electrically and optically. By replacing standard Ni/Au contacts to p-GaN with Ni/Al layers, the LED output power emission through the sapphire substrate was enhanced by a factor of 2-4, with no significant impact on the operating voltage.
