Abstract
We report the crystal and band gap structures of copper(II) phthalocyanine (Cu–Pc) thin films depending on the substrate heating conditions and temperatures. The phase changes of the two α- and β-phases of Cu–Pc thin films due to different heating conditions were observed by using X-ray diffractions and electronic absorption spectra. As the temperatures increased from room temperature to 300°C, the energy gap was changed from 1.8052 to 1.7844eV and the crystal structure of Cu–Pc thin films was transformed from orthorhombic α-phase to monoclinic β-phase. The orientation of grains depended on the heat-treatment conditions and the temperatures of the substrate during film deposition. The transport properties of Cu–Pc thin films with different grain orientations were studied.
