Description	The influence of atomic hydrogen on the Si(100) substrate with submonolayer gallium surface phases - (2x3), (2x2) and (8x1) - as well as the deposition of gallium on monohydride terminated Si(100)-(2x1)-H surface were studied by synchrotron radiation photoelectron spectroscopy (SR-PES) and low energy electron diffraction (LEED) and compared with similar metal/Si systems. It was found that gallium deposition on the Si(100)-(2x1)-H surface at elevated temperature (400 C) leads to a complete hydrogen desorption and formation of the same gallium surface phases as on the bare Si(100)-(2x1). Exposing the Si(100) substrate with (2x3)-Ga and (2x2)-Ga surface phases to atomic hydrogen results in the formation of gallium nanoclusters, surrounded by the Si(100)-(2x1)-H surface. These clusters have more than 2 monolayers in height and cover approximately 20 - 26 % of surface, depending on the initial coverage. The results indicate that the cluster size and density may be controlled by initial Ga coverage and poss The influence of atomic hydrogen on the Si(100) substrate with submonolayer gallium surface phases - (2x3), (2x2) and (8x1) - as well as the deposition of gallium on monohydride terminated Si(100)-(2x1)-H surface were studied by synchrotron radiation photoelectron spectroscopy (SR-PES) and low energy electron diffraction (LEED) and compared with similar metal/Si systems.
