An ultrahigh vacuum chemical vapor deposition (UHV/CVD) system is introduced. SiGe alloys and SiGe/Si multiple quantum wells (MQWs) have been grown by cold-wall UHV/CVD using disilane (Si 2H 6) and germane (GeH 4) as ...
Abstract: The optimum parameters are calculated by the large cross - section theory and mode cut - off equation. The effect on reverse bias voltage is analysed by the doping concentration in n+ - Si. This is significa...
