Tunnel/jump electroconductivity in the laser-induced nanocluster structures with controlled topology
- 89 Downloads
By method of laser-induced thermal deposition of colloidal particles laser we have produced the metallic granular films for which the ability to control the change in its electrical properties does exist by variation of the topology for the system. The quantum states verification in cluster metallic structures by jump/tunneling electroconductivity and possible mechanisms for its implementation are considered in experiment and theory. The granular conductivity specificity has been under study. The current–voltage characteristics behavior has been measured for a gold (Au) and Au-carbyne clustered film. 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.
