摘要：
An interpretation of the constant-current STM image of a Cu-phthalocyanine molecule adsorbed on a Cu(100) surface is proposed based on an extension of the elastic scattering quantum chemistry (ESQC) technique to simulate STM images. After a brief description of the method, the dependence of the Cu-phthalocyanine image on the tip structure and the Fermi level is presented. The way in which atom positions of an adsorbate can be extracted from an experimental STM image using the STM-ESQC technique is also discussed.
