Outline of Final Research Achievements

Details of the charge transport properties of mixed-valence metal oxide clusters are investigated with changing intercluster distance by employing their counter cation. Crystallographic analysis revered relation between n and inter-cluster distances and the conductivities were found to decrease with increasing alkyl chain length of the counter cation, which was explained by considering the conductivity as a function of both temperature and inter-cluster distances.
