(Color online) XPS and UPS measurements of neat and different mixed films of and CuPc: (a) C spectra (excitation: monochromated ), (b) HOMO levels (excitation: ), and (c) secondary electron cutoff (excitation: and ). The numbers on the right side of the diagrams give the concentration as determined from the measurements shown in part (a).

FIG. 2.

(Color online) Positions of the energy levels (vacuum level, high energy edge of the HOMO level, and C and N core levels) depending on the mixing ratio. The ● and the ◆ symbols represent the measured values for and CuPc related levels, respectively, and the ▴ symbols the measured work functions. The (———) lines are linear fits of the corresponding measured values. The constant (∙ ∙ ∙) is the vacuum energy of the conductive hydrocarbon layer on gold. The (- - -) lines are the calculated LUMO levels.
