Publikováno v: Solid State Phenomena. 92:41-44
The stability of three complexing agents, HEDP, CDTA and DTPMP, in the SC-1 bath was determined. The feasibility of using capillary electrophoresis (CE) and electrospray ionization mass spectrometry (ESI/MS) for such studies was assessed. CE was empl

Electrochemical quartz crystal microbalance study of the electrodeposition mechanisms of Cu2−xSe thin films
Autor: Marianna Kemell, Markku Leskelä, Mikko Ritala, Heini Saloniemi
Publikováno v: University of Helsinki
Scopus-Elsevier
Electrodeposition mechanisms of Se, Cu and Cu2−xSe thin films were studied by means of the electrochemical quartz crystal microbalance (EQCM). The electrodeposition of Se was found to be faster at higher overpotentials, though with lower apparent e
