AlGaAs/InGaAs metal-oxide-semiconductor pseudomorphic high-electron-mobility transistor with a liquid phase oxidized AlGaAs as gate dielectric
The investigation describes AlGaAs/InGaAs/GaAs metal-oxide-semiconductor pseudomorphic high-electron-mobility transistors (MOS-PHEMTs). The gate dielectric is obtained by oxidizing AlGaAs in liquid phase. The MOS-PHEMTs have a larger gate swing voltage. a lower gate leakage current and a higher breakdown voltage than their counterpart PHEMTs do. (C) 2004 Elsevier Ltd. All rights reserved.
