Atomic force microscopy and micro-Raman scattering techniques were used to investigate self-assembled nanoislands in heteroepitaxial GeSi systems. The temperature increase showed strong enhancement in the surface diffusion of Si atoms from the substrate to the islands, giving rise to a wider stability range of pyramid-shaped volumes. The results showed that a high concentration of Ge islands were obtained on Si(100) surfaces with a narrow size distribution, at low temperatures.
