Abstract
Various defects, registered by scanning tunneling microscopy (STM) on surfaces of single crystals of different bis(ethylenedithio)tetrathiaf ulvalene, BEDT-TTF, salts are characterized. In the large scales (up t o 100X100 mu2) microcracks and terraces, formed by multiple steps of s urface layers are the dominating morphologic features. In the atomic-s cale STM images the observed imperfections are mainly related with vac ancies in the crystallographic ionic lattice. They are formed by misin g cations or anions. Other types of defects such as crystal twinning a nd linear dislocations have been also visualized.
