Formation and characterization of Sb2Te3 nanofilms on Pt by electrochemical atomic layer epitaxy

Article Abstract:

The electrochemical formation of nanocrystalline Sb2Te3 thin films on a Pt substrate through the route of electrochemical atomic layer epitaxy (ECALE) and the electrochemical behavior of Te and Sb on Pt, Te on Sb-covered Pt, and Sb on Te-covered Pt are described. The optical band gap of the deposited Sb2Te3 film is determined as 0.42 eV by FTIR spectroscopy and it is blueshifted in comparison with that of the bulk Sb2Te3 single crystal because of its nanocrystalline microstructure.

MoS(sub 2) nanostructures: Synthesis and electrochemical Mg(super 2+) intercalation

Article Abstract:

MoS(sub 2) nanostructures including hollow-cage fullerene-like particles, fibrous floccus, and spherical nanovesicles are synthesized by designed solution chemical reactions of Na(sub 2)MoO(sub 4) and sulfurization reagents. The electrochemical properties of annealed MoS(sub 2) samples are investigated as Mg(super 2+) ions showed better reversibly intercalation/deintercalation cycles in as-synthesized MoS(sub 2) nanostructures than in bulk MoS(sub 2) samples.

Adlayers of Sb irreversibly adsorbed on Pt(111): An electrochemical scanning tunneling microscopy study

Article Abstract:

An electrochemical scanning tunneling microscopy (STM) is used to study the adlayers of Sb irreversibly adsorbed on Pt(111) at various potentials. The changes in the voltammograms of irreversibly adsorbed Sb on Pt(111) are described in conjunction with the electrochemical scanning tunneling microscopy (EC-STM).
