Comparative investigation of underpotential deposition of Ag from aqueous and ionic electrolytes: An electrochemical and In situ STM study
Article Abstract:
Underpotential deposition (UPD) of Ag on Au(111) is studied with two different electrolytes such as aqueous 0.1 M H(sub 2)SO(sub 4), solution in comparison with the ionic liquid 1-butyl-3-methylimidazolium chloride BMICI plus AlCl(sub 3). Cyclic and linear sweep voltammetry in combination with situ electrochemical scanning tunneling microscopy (STM) is used to investigate the distinct behavior of 2D phase formation at both interfaces.

Microscopic and electronic structure of semimetallic Sb and semiconducting AlSb fabricated by nanoscale electrodeposition: An in situ scanning probe investigation
Article Abstract:
A study on the nanoscale electrocrystallization of pure Sb and the compound semiconductor AlSb on Au(111) is conducted by in situ scanning probe techniques (STM and STS). Conductance spectra of these clusters display the main features of the electronic structure of the bulk semiconductor AlSb, with a band gap of 2.0 plusmn 0.2 eV.

Pulsed electrodeposition of two-dimensional Ag nanostructures on Au(111)
Article Abstract:
The two-dimensional (2D) phase formation and growth of Ag on Au(111) are studied under pulsed electrodeposition conditions in comparison with conventional underpotential range (UPD). The evolution of the 2D nanostructures as a function of time and potential is followed by in situ scanning tunneling microscopy (STM).
