Collaborations in year 2010-2011 Research Contents Research Topics Metal nano-structure ultrafast time-resolved measurement Ultrafast optical imaging exhibits a structure-dependent ps time-response. Heterocyclic oligomer structure Low-dimensional conjugated electronic structure possesses for optoelectronic application a strong exciton density-dependent ps relaxation time. Multiferroics materials for Optimum doping level for the minimum leakage current spintronic application is identified. 16
