摘要：
Superstructure was observed on the surface of the organic conductor beta-(BEDT-TTF)2I3 [where BEDT-TTF is bis(ethylenedithio)tetrathiafulvalene] by scanning tunneling microscopy; this shows that surface reconstruction for organic materials can occur. The column structure of BEDT-TTF molecules along the [011] direction was stable and the reconstruction was completed as a result of the change in the relative arrangement of these columns. Many defects consisting of the voids of the BEDT-TTF molecules were also observed. These imperfections of the crystal surface are considered to be due to the instability of the anion structure.
