Growth of SiGe Films by Cold-wall UHV/CVD Using GeH_4 and Si_2H_6
《Semiconductor Photonics and Technology》2000年第3期134-138,共5页CHENGBu-wen LIDai-zong  
ChineseHigh -TechnologyResearchPlan (No .863- 30 7- 15- 4 ( 0 3) )andChineseNaturalScienceFund (No .698962 60 )
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 ...

Calculation of Ge_(0.5)Si_(0.5)—Si Superlattice Photodetectors on Ge_(0.05)Si_(0.95) Waveguides:The Optimum Parameters
《Semiconductor Photonics and Technology》1997年第1期3-6,共4页XU Xuelin, LI Na, LIU Enke(Xi’an Jiaotong University, Xi’an 710049, CHN ) 
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...
