Abstract

In this paper we report the influence of H2 on Ge surface segregation in Si/SiGe heterostructures. The sample were grown on Si(001) substrate tinder different gas flow of H2 by RTP/VLP-CVD. Auger electron energy spectroscopy(AES) has been used to determine the Ge distribution in Si/SiGe heterostructures. The results indicate that H2 can strongly alter the mechanism of Ge surface segregation and change the distribution of Ge atoms.
