抜粋

We demonstrate improved characteristics of GaInN light-emitting diodes (LEDs) grown on Si by a horizontal metalorganic chemical vapor deposition method. A high-temperature-grown thin AlGaN/AlN intermediate layer and AlN/GaN multilayers have been used for the growth of a high-quality LED structure on Si substrate. The green LED on Si exhibited a forward voltage of 4.1 V at 20 mA and a series resistance of 30 Ω. The output power of 18-20 μW was obtained at 20 mA, which was approximately half that of LED grown on sapphire. The AlGaN/GaN high electron mobility transistors (HEMTs) were also realized on Si substrates. The 2-um-gate length AlGaN/GaN HEMT showed a good maximum extrinsic transconductance of 142 mS/mm.
