چکیده انگلیسی
We have studied epitaxial growth of Ge1âxSnx and SiyGe1âx-ySnx materials in 200Â mm and 300Â mm industrial CVD reactors using industry standard precursors. The growth kinetics of undoped GeSn were firstly studied via varying growth parameters including growth temperatures, GeH4and SnCl4precursor flows, which indicated that the material growth is highly dependent on surface kinetic limitations involving the SnCl4reaction pathway. Secondly, the growth kinetics of doped layer growth by varying the growth temperatures and the PH3and B2H6dopants flows were investigated. It was shown that B2H6had the effect of increasing the growth rate and decreasing the Sn incorporation whereas PH3had no effect on the growth rate but increased the Sn incorporation. Thirdly, the SiGeSn growth kinetics using SiH4, GeH4, and SnCl4as precursors were discussed, which revealed that the careful control of the growth rate was required to produce compositionally homogenous SiGeSn alloy. Moreover, the material and optical characterizations have been conducted to examine the material quality. Finally, the GeSn quantum well structure was grown to exhibit the precise control of the growth parameters.
