Abstract
The properties of copper-phthalocyanine (CuPc) thin films vacuum evaporated on glass substrates under different electric fields have been investigated. The resistances of the film decrease rapidly with increasing electric fields. The results of AFMs, XPS and X-ray diffraction reveal that electric fields change the chemical environment of Cu and increase the order of copper phthalocyanine molecules. A possible mechanism of this phenomenon is discussed in this paper.
