Abstract
Electronic phase separation consisting of the metallic and insulating domains with 50–100 μm in diameter is found in the organic Mott system κ−[(h8−BEDT−TTF)1−x(d8−BEDT−TTF)x]2Cu[N(CN)2]Br by means of scanning microregion infrared spectroscopy using the synchrotron radiation. The phase separation appears below the critical end temperature 35–40 K of the first-order Mott transition. The observation of the macroscopic size of the domains indicates a different class of the intrinsic electronic inhomogeneity from the nanoscale one reported in the inorganic Mott systems such as high-Tc copper and manganese oxides.
