Preparation of pseudomorphic Si1−yCy/Si(001) heterostructures using Si molecular beam epitaxy with C obtained from SiC sublimation in a high-temperature cell has been studied. Thick ((approximate)2000 Å) homogenous Si1−yCy layers, y≤1.5%, and Si1−yCy/Si multiple quantum well (MQW) structures, y≤8%, have been prepared. There is a growth temperature dependent surface roughness accumulating during the growth sequence that can lead to reduction of C induced strain. Temperature modulation during growth has been used to suppress this effect. Near band gap photoluminescence is reported from Si1−yCy/Si MQW structures. © 1997 American Institute of Physics.
