Si-substitutional defects on the .alfa.-Sn/Si(111)-(.sqrt. 3 x. sqrt. 3) surface

We use a first-principle DFT local-orbital method and analyze Si-defects on a large Sn/Si(111) surface unit-cell, corresponding to a defect concentration as low as 3.7%......

Role of Dangling Bond State Occupancy in Adsorption of Copper Phthalocyanine on Si(111)-Sn-root 3 x root 3

Interaction of organic molecules with solid surfaces reflects the local electronic structure of nonequivalent surface sites. The Si(111)-Sn-root 3 x root 3 in the reactivity of the Si(111...

Scanning tunneling spectroscopy investigation of the (3x3)R30o Sn/Si(111) and .gamma. surfaces

Scanning tunneling spectroscopy (STS) has been used to investigate the electronic structure of the 1/3 ML Sn1 - xSix/Si(111) 2D alloy at 300 K for the two limiting cases of x:0 and x=0.5 corresponding to the alfa and .gamma. (or mos...

Mobility of Single Sn Atoms Inside Si(111)-7x7 Half-unit Cells

Low coverage phases of Sn on Si(111)-7x7 were investigated by scanning tunneling microscopy. At room temperature, a single Sn atom is highly mobile inside a half-unit cell of the surface reconstruction. It...

Anomalous structural evolution and 3 x 3 reconstruction of a clean Si(111) surface observed after thermal desorption of thallium

The authors have observed anomalous structural evolution of a clean Si(111) surface, which was prepared first by thallium (Tl) deposition on a Si(111)7??7 surface, leading to incomplete formation ...
