【 摘 要 】

The quantum states verification in cluster semiconductor/metallic structures by jump/tunneling electroconductivity and possible mechanisms for their implementation are considered in experiment and theory. By our laser ablation technique we have nanostructurized the films for which the ability to control the change in their electrical properties does exist by variation of the topology for the system. The granular conductivity specificity has been under study. The current-voltage characteristics behavior has been measured for a nanocluster bimetallic film (Au+Ag), and the experiments for multilayer bimetal thin films of the different composition have been carried out. Two associated mechanisms for electroconductivity occur in the case, i.e. tunnel transition for electrons and electron activation in the frames of the shell model for a cluster system, in dependence on the nanostructure topology.
