Abstract
A new class of Si-based quantum confined geometry is demonstrated usin g a combination of oppositely strained layers grown on a step-graded r elaxed SiGe buffer. The role of heterointerfaces is revealed as the co ntrolling mechanism of the exciton localization, which results in enha nced no-phonon transition intensity. (C) 1996 American Vacuum Society.
