My research subject is theoretical studies of structural and electronic properties
of overlayers on semiconductor surfaces

  • In particular, I have been working on S and H2S-molecule adsorbed on the InP(110), GaAs(110), GaP(110), Si(001) and Ge(001) surfaces. ( H2 S-Si(001)-(1x2))
  • I have been working on disilane and digermane on the Si(001) and Ge(001) surfaces. Surface processes during chemical vapor deposition and the atomic-layer epitaxy of group-IV elements currently have received extensive interest. Although this process is most important for the microelectronics industry, a detailed theoretical understanding of these surfaces has not been investigated.
  • I am using an ab initio pseudopotential LDA code developed by my supervisor Dr. G.P. Srivastava.
