Abstract

In this paper we present a study of the structure, composition and optical properties of SiGe quantum dots grown by gas-source molecular beam epitaxy on Si (001). Atomic force microscopy (AFM), transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), energy dispersive X-ray analysis (EDX), photoluminescence (PL) spectroscopy and decay time measurements of the quantum dots suggest that there are two distinct sizes of quantum dot, contributing two distinct emission bands in the PL spectra.
