Виктор Климов И

Victor I. Klimov is a Fellow of Los Alamos National Laboratory (LANL), Director of the Center for Advanced Solar Photophysics (CASP), and leader of Nanotechnology and Advanced Spectroscopy team in the Chemistry Division of LANL. Victor completed his graduate studies in Russia at Moscow State University (MSU) specializing in condensed matter physics and laser optics. After defending his Ph.D. thesis in 1981, he joined the Moscow Institute for Geodesy, Mapping, and Aerial Photography as an Assistant Professor. At the same, he continued his research at the Physics Department of MSU pursuing an advanced scientific degree of Doctor of Sciences (D.Sc.). After successfully defending this degree in 1993, Victor moved to Germany and joined the Technical University of Aachen, Germany as a Humboldt Research Fellow. In 1995, Victor moved to the US and joined LANL as a Technical Staff Member. The focus of Victor’s recent research has been on multiexciton phenomena in semiconductor nanocrystals. Among other results, this work established that the dominant decay channel for multiple electron-hole pairs in nanocrystals is extremely fast, nonradiative Auger recombination (Science 287, 1011, 2000). This discovery was critical for the first demonstration of lasing in colloidal quantum dots reported by his team in 2000 (Science 290, 314, 2000). Using the distinct Auger-decay signature of multiexcitons in nanocrystals, Victor’s team was the first to experimentally demonstrate high-efficiency carrier multiplication (multiexciton generation by single photons) in 2004 (Phys. Rev. Lett. 92, 186601, 2004). This discovery has stimulated a broad worldwide effort focusing on the fundamental physics and practical applications of this phenomenon. Other novel ideas introduced by Victor and his team include the concept of singe-exciton lasing (Nature 447, 2007), “wireless” energy-transfer pumping of nanocrystals (Nature 429, 2004), and 'blinking-free' quantum dots (J. Am. Chem. Soc. 2008).
