摘要

The electronic and magnetic properties of (Au, Tl) doped C_(60) fullerene are investigated with ab initio density functional theory calculations by using a program code, known as SIESTA which is based on the standard Kohn-Sham self-consistent density functional theory (DFT). The pseudopotentials are constructed using a Trouiller-Martins scheme, to describe the interaction of valence electrons with the atomic cores. In endohedral doped Au_n (n = 1-6) and Tl_n (1-4) complexes we have seen that they are stable and there after cage break down. We have also investigated that binding energy and ionization potential decreases while electronic affinity increases and magnetic moment with increase in number of semiconductor atoms in C_(60) fullerene. No systematic pattern could be observed for HOMO-LUMO gap.
