Electrical and photoelectrochemical characterization of CdS particulate films by scanning electrochemical microscopy, scanning tunneling microscopy, and scanning tunneling spectroscopy

摘要

Cadmium sulfide particulate films have been generated at monolayer interfaces. Controlled and infusion of hydrogen sulfide onto compressed monolayers prepared from cadmium arachidate resulted in the formation of covalent metal sulfide bonds at a large number of sites at the monolayer-aqueous interface. The initial nucleation resulted in the downward growth of well-separated, metal-sulfide microclusters which grew in height and width and coalesced into interconnected arrays of semiconductor particles.
