Outline of Final Research Achievements |
Macroscopic inhomogeneity due to the strongly correlated electrons in BEDT-TTF system was investigated by optical measurements. The phase separation between metal and insulator domains and its dynamics in charge ordered salts were observed by mid-infrared microscopy with synchrotron radiation. In addition, the spatial symmetry breaking in dimer-Mott type salts was investigated by femtosecond-pulse-induced terahertz emission spectroscopy.
