|Title:||Electrical properties of chloroaluminium phthalocyanine thin film sandwich devices|
|Authors:||E- Azimaraghi, M|
|Abstract:||Spectroscopic measurements in the range 10 kHz - 6 MHz at different temperatures are reported for Au/ClAlPc/Au thin film sandwich devices. The ac conductivity was found to vary with the angular frequency ω. In the high frequency region, the ac conductivity is proportional to ωⁿ. The capacitance and loss tangent decrease with increasing frequency and the capacitance increases with increasing temperature. The results show that the relative importance of the hopping model and band theory in describing the film conduction with regard to the operating conditions. The band theory is dominant at high temperatures and low frequencies, whereas hopping model is dominant at high frequencies and low temperatures.|
