The aim of the project is to participate, together with a number of European groups, on a coordinated Action of COST MP0805. This Action is concentrated to study in a complex way the semiconducting materials of the type III-N-V for the purposes of communications. In the context of this activity the present project wants to perform the theoretical basic research of relaxation effects, transport and the influence of the interaction of charge carriers with the vibrations of the lattice, especially in connection with the new knowledge achieved within the Action, as is the band structure, scattering mechanisms, and others. The purpose of the project will contain also the explanation of properties of nanostructures of III-N-V materials including nanodevices. An attention will be paid to organic components in the nanostructures as well. (en)

Proces mocninného časového útlumu intensity fotoluminiscence v malých kvantových tečkách s tzv. nepřímým gapem byl vysvětlen pomocí interakce elektronů s podélnými optickými fonony. Bylo zjištěno, že proces přenosu energie v hybridních organicko-anorganických systémech se skládá současně z nerezonanční a rezonančí složky vibronického přenosu. (cs)
The process of the power-law time dependence of the photoluminiscence intensity decay in small quantum dots with the indirect gap was explained on the basis of the electronic interaction with longitudinal optical phonons. The process of energy transfer in the hybrid organic-inorganic donor- acceptor system was found as to be formed simultaneously by the non-resonant and resonant vibronic parts (en)
