Abstract

Soft x-ray photoelectron spectroscopy was performed for α-TDAE-C 60 single crystal. A C 1s spectrum with a shakeup satellite of TDAE-C60 is very similar to that of C60 when we shift the energy, indicating a charge transfer to the C60 site. A comparison of a N 1s spectrum with theoretical calculations indicates that TDAE mainly consists of the TDAE+ state. The valence-band spectrum near the Fermi edge also suggests a charge transfer from the TDAE to the C60 cage. Based on these results we propose a modified model for the charge transfer: the charge states of C60- and TDAE+, and the dimer formation along the c axis between the TDAE+ states.
