摘要：

We have studied the electronic structure of potassium-doped copper phthalocyanine (CuPc) using photoemission spectroscopy. A detailed analysis of the core-level spectra allows us to propose possible lattice sites for the potassium ions. None of the films prepared in our studies showed a finite electronic density of states at the Fermi level (E-F), which is in contrast to reports in the literature. Possible reasons for this discrepancy are discussed. (c) 2005 American Institute of Physics.
