| Abstract: | Self-Oxidic film on AlGaAs/GaAs has been made by means of anodic oxidation processing, thus, MOS structure is formed in a further step. The stability and composition of oxidic film and the C-V characteristics of MOS structure have also been tested and analysed theoretically in this paper. Experimental results indicate: the oxidic film will be stable in electric properties after annealing in nitrogen ambient. The MOS structure is suitable for deep level trancient spectroscopy and the measuring conditions for MOS DLTS measuremens are presente din this paper. |
