Nanotechnology and Advanced Spectroscopy
The research of this team centers on the synthesis and characterization of semiconductor and metal nanoparticles, composites and assemblies, and their application in optoelectronic devices. This world-recognized effort is fully integrated, combining extensive wet-chemical synthesis and assembly capabilities with nearly unmatched advanced spectroscopic resources. The LANL component of the new Center for Advanced Solar Photophysics is housed in this team.
Center for Advanced Solar Photophysics (CASP), is a
DOE Energy Frontier Research Center.
The goal of this center is to explore and exploit the unique physics of nanostructured materials to boost the efficiency of solar energy conversion through novel light-matter interactions, controlled excited-state dynamics, and engineered carrier-carrier coupling. Examples of phenomena that are studied in the center include field enhancement in metal nanostructures for improved light-harvesting and high- efficiency coupling schemes, quantum confinement in semiconductor nanostructures for tailoring absorption spectra and directional transport in energy-gradient assemblies, and strong electron-electron interactions in quantum confined materials for increased photo-generation rates via carrier multiplication. One recent advance is solar cells made with low-cost, nontoxic copper-based quantum dots that achieve unprecedented longevity and efficiency.
Victor Klimov, leader of the quantum dot team, received the Alexander von Humboldt award. Klimov is an expert in nanocrystal quantum dots and optical amplification in nanocrystals. He will conduct research at Dresden University of Technology and the Ludwig Maximilian University of Munich during 2013 and the summer of 2014.
