| Si(100) surface is reconstructed in 2x1 structure, where two adjacent surface Si atoms form dimers. Hydrogen molecules can adsorb on the top Si atoms; one H on each Si atom up to coverage 1 ML. Above this coverage, The dimer structure is rearranged to form local 3x1 structures. | Si(100) surface is reconstructed in 2x1 structure, where two adjacent surface Si atoms form dimers.

| The TPD spectra feature two majour peaks. The alpha-peak appears for initial coverage over 1 ML. This peak is considered to correspond to the desorption from di-hydride states. Only the beta-peak is observed for initial coverage below 1 ML. This peak is considered to correspond to the desorption from mono-hydride states. | The TPD spectra feature two majour peaks.
