Reconstructed Au (100) Surface Imaged with Scanning Tunneling Microscopy in Air

Scanning Tunneling Microscopy, Tunneling Spectroscopy, and Photoelectrochemistry of a Film of Q-CdS Particles Incorporated in a Self-Assembled Monolayer on a Gold Surface

Films of AOT-capped (AOT = dioctyl sulfosuccinate) cadmium sulfide nanoparticles (Q-CdS) prepared by incorporation into a self-assembled monolayer (SAM) of hexanethiol on Au were prepared. These were imaged at negative substrate bias in air by scanning tunneling microscopy, and Q-CdS particles were shown to cover most of the area on the S A M . Continuous scanning of the tip over the substrate ...

In situ Real-time Monitoring of Electrochemical Ag Deposition on a Reconstructed Au(111) Surface Studied by Scanning Tunneling Microscopy

Electrodeposition of Ag and Pd on a Reconstructed Au(111) Electrode Surface Studied by In situ Scanning Tunneling Microscopy

Electrochemical deposition of Ag and potential-induced structural change of the deposited Ag layer on a 23 3  reconstructed surface of Au(111) electrode were followed by in situ scanning tunneling microscope (STM). A uniform Ag monolayer was formed on a reconstructed Au(111) surface in a 50 mM H2SO4 solution at +0.3 V (vs. Ag/AgCl) after adding a solution containing Ag2SO4 so that the concentr...

Characterization of metal clusters (Pd and Au) supported on various metal oxide surfaces (MgO and TiO2)

Au clusters supported on the TiO2~001!/Mo~100! surface and Pd clusters supported on the MgO~100!/Mo~100! surface have been studied using temperature programmed desorption, ion scattering spectroscopy, scanning tunneling microscopy, and scanning tunneling spectroscopy. Three dimensional growth has been observed at 300 K for both cases. The adsorption energy of Au on the TiO2~001! surface has bee...

Initial Nucleation of Au on the ( √ 2 × √ 2 ) R 45 ◦ Reconstructed Fe 3 O 4 ( 001 ) Surface

The initial nucleation of Au onto the ( √ 2× √ 2)R45◦ reconstructed Fe3O4(001) surface has been studied using scanning tunneling microscopy. Au clusters are formed, with a typical lateral dimension of ∼ 9 Å. The measured corrugation height of the clusters, ∼ 1 Å, suggests that they are a single atomic layer in height. The clusters nucleate on a specific surface site, which lies at the centre of...
