G. Lippert et al., ENHANCEMENT OF SUBSTITUTIONAL CARBON INCORPORATION IN HYDROGEN-MEDIATED PSEUDOMORPHIC GROWTH OF STRAINED ALLOY LAYERS ON SI(001), Journal of crystal growth, 175, 1997, pp. 473-476
The reduction of strain in SiGe layers on Si substrate is possible by
the substitutional incorporation of carbon into the SiGe lattice. The
carbon incorporation depending on various growth parameters could be i
mproved by an additional hydrogen residual atmosphere during MBE. Grow
th temperature in the range between 400 degrees C and 550 degrees C su
pports the amount of substitutional carbon in silicon.
