Abstract

The application of an electric field to induce the orientation of CdSE nanorods that were self assembled in the poly(4-vinylpyridine) (P4VP) nanodomains of a diblock copolymer thin film was discussed. The number of CdSe nanorods incorporated in the P4VP nanodomains varied by controlling the strength of the polar interactions and the loading concentration. The electron mobilities and the electron-barrier heights of the CdSe/P4VP nanodomains incorporating out-of-plane and in-plane CdSe nanorods were also monitored. The results show that the electron mobility increased upon increasing the number of CdSe nanorods in both the out-of-plane and in-plane cases.
