Part of the NATO Science for Peace and Security Series B: Physics and Biophysics book series (NAPSB)


In this work the statistic theory of multiple exciton generation in quantum dots based on the Fermi approach to the problem of multiple elementary particles generation at nucleon-nucleon collisions is generalized taking into account the generation of phonons along with electrons and holes. Size and shape optimization of quantum dot has been performed to receive the maximum multiplicity of MEG effect. The role of interface electronic states of quantum dot and ligand has been considered by means of quantum mechanics approaches. Besides the resonance tunneling of electrons and holes through interface described by two barriers potential well has been considered in the classical approximation. The efficiency of photon energy conversion into electrical one at presence of MEG effect in QDs has been calculated in the frame of Fermi statistical mechanism. The process of fast decay of exciton in polymer matrix by effective acceptor doping has been theoretically analyzed by means of Migdal’s approach in weakly ionized plasma.
