AbstractA scanning tunneling microscopy (STM) has revealed an atomic structure of Si(111)-√3× √3R30° which is induced by the hydrogen desorption at about 500 °C. There exist domains with the √3× √3R30° structures, indicating that each domain is formed by rearrangement of Si adatoms around each cluster present at room temperature. Near the domain boundary, the adatoms locate mostly at T4 sites and occasionally at H3 sites. The dynamic nature of the adatoms are predicted.

ABSTRACTWe demonstrate scanning tunneling microscopy studies of a Si(001)-c(4×4) structure which consists of a considerable number of dimer vacancies (missing dimers). Two different preparation methods are examined; one is hydrogen desorption and another is a special annealing and cooling process without hydrogen. The STM images reveal that atomic structure of the c(4×4) prepared without hydrogen is quite different from that prepared with hydrogen and is well described by the missing dimer model. A moiré-like pattern is observed on the c(4×4) surface prepared by hydrogen with an increase in the tip-sample distance, which suggests that the atoms lying in the subsurface should be considered for the precise description of the c(4×4) structure.

The effect of deposition time on the surface coverage of sublimation deposited solid-phase glycine and proline molecules onto a Ge(100) surface was studied at room temperature using scanning tunneling microscopy (STM). The STM images obtained at various coverages of glycine and proline adsorbed on the Ge(100) surface showed that (i) the adsorption rate for both molecules gradually decreased with increasing deposition time, obeying the Langmuir adsorption model, and (ii) the coverage of glycine on the Ge(100) surface is higher than that of proline under the same deposition conditions, which may be due to the differences in their molecular weight or molecular sticking probability.
