Abstract

Interface states density (Nss) and minority carrier generation lifetime (τg) were evaluated in detail for strained Si/SiGe wafers by deep-level transient spectroscopy and metal-oxide-semiconductor transient capacitance methods. Nss shows a nondependence on strained Si thickness (dsi) within a critical thickness and a clear dependence on Ge fraction (Ge%). τg shows a strong dependence on both dsi and Ge%. The reasons for these dependences are discussed in detail.
