Abstract

SiGe alloy quantum dots with spherical shape have been synthesized by the thermal evaporation method. The shape and structure of these dots have been investigated. Transmission electron microscopy images show that they have an average diameter of about 15 nm, and their cores are crystalline. The composition of these dots could be extracted from the Raman peak position of the silicon TO phonon.
