Abstract
The molecular orientation of Vanadyl-Phthalocyanine (VOPc) grown on al kali halides was studied by Angle-Resolved Ultraviolet Photoelectron S pectroscopy (ARUPS). To avoid charging up of the specimen during ARUPS measurement, thin epitaxial films of alkali halides grown on GaAs (00 1) were used as substrates. Photoelectrons emitted from the highest oc cupied molecular orbital band of VOPc showed strong angular distributi on leading to the conclusion that the molecules stay almost parallel o n the surface. This was in accordance with the expectation based on th e reflection high-energy electron diffraction analysis of the film.
