“…The values of hole mobility obtained in this work may be compared with those reported by Riad [23] These values appear to be reasonable in that they are of the same order as those deduced by other workers [15,17,21].…”

Si-Phthalocyanines (SiPc) thin films were deposited on conductive substrates and their electronic properties were studied in sandwich-like Metal-SiPc-Metal structures. The current-voltage characteristics at different temperatures were determined. Aluminum and gold were used as electrode metals. For the Au-SiPc-Au structures, the J-V results were interpreted by using the space-charge-limited-conductivity theory and subsequently the trap density and hole mobility in the SiPc volume were determined. For the Al-SiPc-Al structure the J-V curves were analyzed based on the Schottky theory and the barrier height value for the Al-SiPc barrier was calculated. Moreover, the current density level flowing through the structure was depending on the polarization (forward o reverse) applied to the structure. This effect was attributed to the possible existence of an oxide at the interface between the top electrode and the SiPc.

“…In particular, spacecharge-limited (SCL) conduction provides useful information on the trap levels in this material. SCL currents have been observed by several workers, generally dominated by traps either at a signal level [4] or within an uniform [5] or exponential [6] distribution in energy. Ou et al [7] have observed a hole trap at an energy of 0.54 eV above the valence band edge of concentration 10 20 m À3 in electrodeposited p-type films.…”

“…The positive charge carrier mobility was estimated and demonstrated that its value was higher for thinner films. Measurements of the temperature dependence of ohmic and SCL currents on thin films of polycrystalline particles of h-magnesium phthalocyanine dispersed in a polymer binder in Schottky junction cells have been carried out by Riad et al [11]. They determined that the conduction process was Schottky emission in the lower voltage range and PF effect in higher voltage levels.…”
