Nanostructure & function in optoelectronic materials
Thin film optoelectronic materials such as organic semiconductors, inorganic semiconductor nanocrystals, and hybrid organic-inorganic lead halide perovskites have applications in lighting, displays, photovoltaics, sensing, and detection. Molecular-scale morphology in the solid state often determines the function and efficiency of energy and electron transfer processes in these materials. The ability to characterize and understand their structure at this scale is key to optimization and control for incorporating novel materials in technologies.
