The surface structure of an organic conductor (BEDT-TTF) 2KHg(SCN) 4 observed by scanning tunneling microscopy
Abstract
The bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) molecules in the surface cation layer of the (BEDT-TTF) 2KHg(SCN) 4 crystal were observed by scanning tunneling microscopy (STM). The obtained arrangement of BEDT-TTF was in good agreement with that expected from the structure determined by X-ray diffraction. In addition, some subsidiary images were observed around the K and Hg ion positions. The STM image of the BEDT-TTF molecules was influenced by the structure of the anion layer on them, and they showed a strong bias dependence.
