摘要
Low noise HEMTs with GaAlAs/GaAs heterostructures have been successfully fabricated using metal organic chemical vapour deposition (MOCVD). Hall mobilities of the two-dimensional electron gas at the interface are 8000 and 148,000 cm**2/Vs at 300 and 77 K. These are comparable to the best results yet reported using molecular beam epitaxy (MBE). The HEMTs fabricated by MOCVD with a 0. 8 mu m-long gate have exhibited a noise figure of 1. 47 dB with 9 dB associated gain at 12 GHz and transconductance of 190 mS/mm.
