Electrically active interface defects in the In0.53Ga0.47As MOS system
The energy distribution of electrically active interface states at the Al2O3/In0.53Ga0.47As interface has been evaluated. Analysis reveals a peak of donor-like interface trap density 1.51013cm?2eV?1 located at ?0.36eV above Ev. Acceptor-like interface traps are also present located in the In0.53Ga0.47As conduction band. The interface state distribution is similar to reports for others oxides. Results suggest the interface states originate from the In0.53Ga0.47As surface.
