Anions Effects in the Underpotential Deposition of Cd on Au(lll),and Formation of the First Monolayers of CdTe,using: AES,XPS,LEED and STM

摘要

The present study investigates Cd UPD on Au (111) from different electrolyte solutions: chloride,sulfate,iodide,acetate and perchlorate.The structure and composition of the atomic layer was analyzed using Auger electron spectroscopy (AES),low energy electron diffraction (LEED) and X-ray photoelectron spectroscopy (XPS) in an ultrahigh vacuum chamber,as well as in-situ scanning tunneling microscopy (STM). In addition,the structures formed in the first few cycles of alternated deposition of Cd and Te were studied.
