摘要：
Low-energy electron transmission (LEET) experiments were performed for the indium/perylene-3,4,9,10-tetracarboxylic dianhydride (In/PTCDA) system prepared by a sequential deposition of PTCDA and In on a MoS2 single crystal surface. The dependence of LEET spectra and the work function change (Deltaphi (phi(film) - phi(substrate)) on the deposition amount of In on the PTCDA monolayer showed that the organic-metal compound of In(4)PTCDA was formed at the In/PTCDA interface. The result is in good agreement with that previously obtained using metastable atom electron spectroscopy. Furthermore, from the temperature dependence of LEET spectra and Deltaphi for the In/PTCDA system, we propose that in the as-grown In(4)PTCDA at room temperature In atoms are - located out of the PTCDA plane, and after heat treatment, it becomes a planer structure.
