Local structure of Sn/Si(001) surface phases
The surface structures of the (6 x 2), c(8 x 4) and (5 × 1 ) phases of Sn/Si(001 ) were studied using the X-ray standing wave technique. Using the (004) and (022) Bragg reflections, we find that the (6 x 2) and c(8 × 4) phases are composed of highly buckled Sn-Sn ad-dimers located 1.58 i above the bulk-like Si(004) surface atomic plane. The Sn atoms occupy two distinct sites with a vertical sep...
متن کاملElectronic Structure of Si/InAs Composite Channels
This paper reports electronic structure calculations on composite channels, consisting of indium arsenide grown on the technologically relevant (001), (011) and (112)-orientated silicon surfaces. The calculations are performed with NEMO 3-D, where atoms are represented explicitly in the spds* tight-binding model. The Valence Force Field (VFF) method is employed to minimize the strain. NEMO 3-D ...
متن کاملElectronic structure of biphenyl on Si(100)
We report the study of both occupied and unoccupied electronic states of biphenyl adsorbed on Si 100 by using synchrotron radiation ultraviolet photoemission spectroscopy, x-ray photoemission spectroscopy, and near-edge x-ray absorption fine structure spectroscopy. The results are compared with calculations of the occupied densities of states. Evidence is given of two main effects: i a down shi...
