Electronic excitations of potassium intercalated manganese phthalocyanine investigated by electron energy-loss spectroscopy

摘要

The electronic excitations of manganese phthalocyanine (MnPc) films were studied as a function of potassium doping using electron energy-loss spectroscopy in transmission. Our data reveal doping induced changes in the excitation spectrum, and they provide evidence for the existence of three doped phases: K1MnPc, K2MnPc, and K4MnPc. Furthermore, the addition of electrons first leads to a filling of orbitals with strong Mn 3d character, a situation which also affects the magnetic moment of the molecule. © 2011 American Institute of Physics Article Outline INTRODUCTION EXPERIMENTAL RESULTS AND DISCUSSION SUMMARY
