Abstract

Copper phthalocyanine (CuPc) film with good orientation is always required when CuPc is to be used as an electronic functional layer in different device applications. In the present study, a magnetic field (∼6 mT) was applied during the vacuum deposition of CuPc. The CuPc film grown under such a magnetic field showed better orientation and a new stacking behavior as shown by X-ray diffraction study (XRD) and atomic force microscopy (AFM). In addition, the film grown under magnetic field exhibited different absorption characteristics in the UV-visible range. This demonstrates the potential of using magnetic field to optimize the growth of CuPc for various applications.
