Abstract :
This paper reports on carrier lifetime in Ge+ implanted Si/Si1-xGex/Si structures extracted from capacitance-transient responses of test MOS capacitors. The emphasis is put on the calculation of effective carrier lifetime in Ge+ implanted regions based on the refined value of the intrinsic carrier density/bandgap due to implanted germanium.
