Directed Synthesis And Doping Of Wide Bandgap Semiconducting Oxide Nanocrystals, Thomas Ross Gordon Jan 2013

Directed Synthesis And Doping Of Wide Bandgap Semiconducting Oxide Nanocrystals, Thomas Ross Gordon

Publicly Accessible Penn Dissertations

Wide bandgap semiconducting oxide nanocrystals are a useful class of materials with high stability and numerous useful properties. In the field of catalysis, high surface area oxides are commonly used as catalytic supports and have been found to be photocatalytically active for the production of renewable fuels. Ultra high vacuum studies of single crystals indicate that the surface structure and faceting of oxides dramatically influence their catalytic properties. For plasmonics applications, degenerately doped oxide nanocrystals may act as low-loss substitutes for metals, but little is known regarding the influence of particle shape or assembly on their optical response. With the ...
