Abstract

The formation of carbon-induced Ge islands has been studied using low-pressure chemical vapour deposition (LPCVD) of Ge on Si(001) at temperatures between 600°C and 700°C. Propane (C ₃H ₈) diluted in He was used as a carbon source. The experiments show that the influence of carbon was most significant for deposition at low growth temperature of the Ge island layer. Small-sized islands with a narrow size distribution could be achieved using a carbon adsorption layer. Compared to a sample grown without this layer, the size distribution was significantly smaller. An enhancement of the growth rate of Ge, as seen from Rutherford backscattering spectroscopy (RBS) will be discussed.
