Microwave N2O plasma oxidation of strained Si1-xGex layers at low temp
erature (<200 degrees C) is reported. The hole confinement in accumula
tion in a metal oxide semiconductor (MOS)-gated SiGe/Si heterostructur
e has been confirmed by both simulation and experiments. Electrical pr
operties are also discussed. (C) 1996 American Institute of Physics.
