Pulsed Laser Deposition of Metal Containing Films on Supported Self-assembled Monolayers. Alonzo Martinez & Bryan Jackson
A variety of metal-containing films deposited on organic monolayers are studied in order to elucidate the nature of the metal-organic interface.The second harmonic (532 nm) of a pulsed Nd:YAG laser is directed onto a rotating and translating metal target located in a diffusion-pumped, high vacuum system.In initial studies, silver was laser deposited on a dodecanethiol film, an alkanethiol self-assembled monolayer (SAM), chemisorbed to Au (111).Annealed gold balls provide the (111) surface. Our foremost goal is to characterize the metal-organic surface by atomic force microscopy (AFM).AFM provides a topographic map of the surface.This map provides long-range morphology of the metal overlayer as well as the atomic resolution necessary to deduce the nature of the interaction between the organic functional group on the SAM and the metal overlayer.Currently, we are working to characterize the nature of the thiol-Au and molybdenum disulfide-organic layer interfaces.
