Adsorption and Thin-Film Adhesion on Single-Crystalline Surfaces: Enthalpies, Entropies, and Kinetic Prefactors for Surface Reactions
Chemical bonding at solid surfaces and interfaces is influential in a wide range of important technological applications including catalysis, fuel cells, batteries, chemical sensors, and device fabrication for microelectronics, computers, solar cells, and all variety of coatings. Adsorption and adhesion energetics are key ...
Polymer / Transparent Electrode Interface Studies with Applications for Organic Solar Cells
The field of organic photovoltaics continues to progress through a combination of improved materials selection and a deeper understanding of operational mechanisms. We contribute to advances in both areas through study of the interface between the semiconducting polymer and the transparent electrode. This interface is the ...
Manganese(II) in Semiconductor Nanocrystals
The following chapters describe the state of II-VI semiconductor nanocrystal preparation. Introduction of transition metal dopants gave rise to new materials and provided an insight into both physical and chemical properties of these semiconductor nanocrystals. Mn(II) and Co(II) dopants were used to probe the spatial position ...
Photodoping of Colloidal Nanocrystals
This dissertation addresses various aspects of photodoping colloidal nanocrystals. Photodoped ZnO nanocrystals were found to be versatile tuneable reducers using both quantum confinement and band-gap engineering with Mg2+ doping to change the conduction band potential. Using photoluminescence of the visible trap and magnetic ...
