Microstructural Evolution And Physical Behavior Of Palladium And Osmium-Ruthenium Noble Metal Films, Wen-Chung Li
Microstructural Evolution And Physical Behavior Of Palladium And Osmium-Ruthenium Noble Metal Films, Wen-Chung Li
University of Kentucky Doctoral Dissertations
Nanostructured noble metals exhibit novel physical, mechanical and chemical behavior, and hold promise for applications such as gas sensing and electron emission. A strong emphasis was placed on the processing and characterization of these materials, in the form of nanoporous or nanocrystalline thin films. Palladium-based and osmium-ruthenium alloys were investigated in this dissertation research and will be presented as follows:
(1) Preparation and Characterization of Nanoporous Metal Thin Films
(2) Characterization of Osmium-Ruthenium Coatings
Nanoporous palladium (np-Pd) thin films were prepared by dealloying co-sputtered palladium-nickel precursor alloys. Nanoporous structures were created with 3-D interconnected ligaments and open pores. Size of …
