Electrochemical and in-situ stm study of the surface alloy formation in the system Au(100)/Cd
(Elsevier, 2014-06)
The Cd UPD process in the system Au(100)/Cd2+, SO4 2− and the involved Au-Cd surface alloy formation have been investigated, using conventional electrochemical techniques and in-situ STM analysis. The voltammetric experiences ...
Spontaneous deposition of Sn on Au(1 1 1): An in situ STM study
(Elsevier Science Inc, 2008-10)
The tin adlayer formed by spontaneous deposition on Au(1 1 1) was characterized by cyclic voltammetry and in situ scanning tunneling microscopy (STM) in sulphuric acid solution. Cyclic voltammetry measurements showed ...
