Paper Abstract

We reported deep-level-free band edge luminescence from strained SiGe/Si multiple quantum well structures grown by conventional solid source Si MBE. No-phonon (NP) transitions due to symmetry-breaking alloy disordering in SiGe layers and transverse optical (TO) phonon replicas were clearly identified. A high quality of crystallinity is essential to the efficient luminescence. The choice of a higher growth temperature, Ts equals 870 degree(s)C, beyond the conventional growth temperature window 400-600 degree(s)C, was found to be important for radioactive recombination in SiGe/Si QWs structures.
