Paper Abstract

Theoretical predictions of electronic and optical properties of short period Si/Ge superlattices are presented. Attention is focused on critical point structure and the effects of the superlattice compositional modulation and the buffer on band edge absorption. The band edge absorption is the main distinguishing feature of the different superlattice configurations. The construction conditions for direct-gap Si/Ge superlattices are specified. Theoretical results are discussed in relation to recent experimental work.
