Strain-induced low dimensional confinement structures

Abstract

We propose here confinement structures similar to heterostructures and superlattices. The present structures can be obtained by applying strain to a single material in a periodic or aperiodic way. The conversion of an indirect gap into an optical active direct or quasidirect gap problem has also been investigated together with the role of zone folding in this phenomenon. © 2008 American Institute of Physics.
