Abstract

Tree distinct terraces are observed on the surface of β-(BEDT-TTF)2I3 [BEDT-TTF is bis(ethylenedithio)tetrathiafulvalene, (C10S8H8)] by scanning tunneling microscopy. The first and second distinct terraces are identified as an I3 layer and a BEDT-TTF layer, respectively. This is verified by the step height and the lateral shift of protrusions between these terraces. As for the third distinct terrace, we propose a model of molecular relaxation in the BEDT-TTF layer, which is reasonable in terms of the interaction between I3 and BEDT-TTF and in terms of the mutual interaction among BEDT-TTF molecules.
