Abstract
For the interpretation of STM and STS data a complex insight on the electronic structure of investigated systems is necessary. Only for a small number of systems can this problem be solved analytically to some approximation. For the wide range of interesting systems, including disordered surfaces, molecules, small particles etc, the electronic structure can only be solved numerically. A numerical model for calculation of the elctronic structure and STM, STS data simulations is described, together with results obtained for C6H6 and copper phthalocyanine (CuPc) on a Cu(100) surface. The comparison between the electronic structures of the benzene ring in C6H6 and CuPc and between two different types of N atoms in CuPc are discussed.Keywords
