Sandwich samples of the type (Au-CdPc-Al) have been fabricated by successive vacuum deposition of gold (Au), cadmium phthalocyanine (CdPc), and aluminium (Al) thin films on glass substrates. Good rectification properties have been observed in the device. Ohmic conduction in the lower voltage range has been identified from the forward bias current density-voltage characteristics at room temperature. At higher voltages, a space charge limited conductivity (SCLC) controlled by an exponential trapping distribution above the valence band edge has been observed. The transport properties of the material at ambient temperature have been obtained from an analysis of the samples in the SCLC region. Schottky emission has been identified at lower voltages from the analysis of the reverse bias characteristics.
