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 ...
Electronic Doping and Trap Reduction of Quantum Dots
Both undoped and doped semiconductor quantum dots (QDs) offer unique opportunities for studying the fundamental physics of quantum confinement. Obtaining a thorough understanding of their physical properties is necessary for development of efficient and robust materials for use in a wide range of applications such as ...
Cross-Conjugated Moieties as Design Motifs for a Class of Novel Electro-Optic Chromophores
Organic electro-optic materials are at the forefront of current photonics applications that enable high speed data transmission, micro-scale sensors, and terahertz applications. Typically linearly conjugated push-pull type chromophores are the primary molecules of choice for various second and third order non-linear optical ...
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 ...
