PIN diodes whose intrinsic region s composed of a strained monolayer superlattice (SLS) have been fabricated by molecular beam epitaxy. The optical and geometrical properties of these structures as a function of the substrate orientation have been investigated. Transmission Electron Microscopy (TEM) and X-ray spectroscopy have been used to characterize the crystalline quality of the samples. The absorption spectra have been measured using photocurrent spectroscopy. Optical transitions extending well into the silicon bandgap have been observed. The type of the transition has been analyzed using envelope function approximation and curve fitting procedures.
