| Research Abstract |
The field-effect transistor using the isolated nanofiber on fine electrodes was developed, and the carrier mobility of the nanofiber was investigated. The mobility was higher value, 5×10^<-2>cm^2/(Vs), than that of a film state, and had strong relation with the crystallinity of the nanofiber. Furthermore, the circuit network of the polythiophene nanofiber was established using branched center units and we clarified the relation between the topological dimension of structures and dimension of the carrier transport in the nanofiber network. In addition, the circuit network of the polythiophene nanofiber using Au colloids as branched center units was fabricated, but the properties of electronic state of Au colloids was not be observed sufficiently in the electric properties of circuit network and this issue was remained to the future work.
