“…In addition to these, it has become a widely selected material in organic light emitting diodes due to its low molecular weight, strong luminescence properties and low cost, and it is also used as the base material for various dyes to adjust the emission color from green to red [16][17][18]. There are many studies on the optical, structural, morphological, and photoluminescence properties of the synthesized Alq 3 film [19][20][21]. However, the electrical properties and the effect of annealing on the produced material were investigated [22].…”

In order to enhance the capacitance of the Al/p-Si metal-semiconductor structure, the Alq 3 thin film was coated between these two layers using the spin coating technique as the interlayer. The electrical conductivity, real and imaginary parts of electric modulus, dielectric loss and dielectric constant parameters were examined at the room temperature by the help of admittance measurements in the 100 kHz to 1 MHz frequency range. The effect of frequency on the dielectric constant and dielectric loss values is negligible at the negative voltage values, up to about 0.8 V, and these values rapidly ascended after 0.8 V. The function of electrical modulus complex has been examined from the point of permittivity and impedance in order to clutch the contribution of the particle border on the relaxation mechanism of the materials. It is established that the examined dielectric parameters strongly correlated with the voltage and frequency. As a result, the changes in the dielectric parameters and electrical modulus due to the varying frequency were described as the results of relaxation process, polarization and surface conditions. Furthermore, it could be stated that the Alq 3 material used in the interfacial layer is a useful material which could be used in addition to the conventional materials.
