Electrical properties and dielectric relaxation of thermally evaporated zinc phthalocyanine thin films

An organic/inorganic heterojunction p-VOPc/n-Si was fabricated and its electrical properties were investigated. Temperature-dependent dark current–voltage (I–V) characteristics of the heterojunction exhibited rectification behaviour with a rectification ratio of 405 at ±1 V and room temperature. The current–voltage characteristics of the cell showed ohmic conduction at low voltages followed by a space charge-limited current (SCLC) conduction dominated by an exponential trap distribution at higher voltages. At room temperature, the series and shunt resistances were found to be approximately 1.4 and 100 kΩ, respectively. Diode ideality factor n was found to be 3.2 at room temperature and dropped to 1.9 at 363 K. Room temperature mobility of vanadyl phthalocyanine (VOPc) was extracted from the I–V characteristics in the SCLC region and was found approximately 15.5 × 10−3 cm2 V−1 s−1. The effective barrier height, ФB, was estimated as 0.77 eV. The effect of temperature, on various heterojunction parameters was recorded under dark conditions and at temperatures ranging from 300 to 363 K.

Random-access memory switches were fabricated by using 70 nm thick spun films of nonperipherally octahexyl substituted lead phthalocyanine (PbPc) molecules sandwiched between indium tin oxide (ITO) substrates and vacuum-deposited aluminum (Al) top electrodes. The reproducible hysteresis behavior in terms of high and low conductance states was observed in the current-voltage characteristics recorded for the device at room temperature, and the on/off ratio for this single layered device was estimated to be as large as 103. The bistable electrical switching effects were attributed to the existence of the depletion layer at the ITO/PbPc and energetically exponential distribution in energy of traps in nonactive region of PbPc films.
