Imaging phase separation near the Mott boundary in the correlated organic superconductors $\kappa$-(BEDT-TTF)${}_2$X

T. Sasaki, N. Yoneyama, N. Kobayashi +2

Electronic phase separation consisting of the metallic and insulating domains with 50 -- 100 $\mu$m in diameter is found in the organic Mott system $\kappa$-[($h$8-BEDT-TTF)${}_{1-x}$($d$8-…
