Characteristics Study of the Insulator Polycarbonate Metal-Polymer-Semiconductor Device

In this work, Metal-Polymer-semiconductor devices (MPS-Devices) have been fabricated using a thin film of Poly carbonate (PC). From characterization of the devices, threshold voltage (VT) and breakdown voltage (VB) were determined.The effect of Polymer films thickness and the temperature on the (VT) and (VB) were studied.The
results show that both voltages increase with increasing Polymer film thickness and decrease with the temperature. Illuminated (I-V) characteristics of the fabricated device were studied also, it was clear that the current and voltage increases with increasing illuminated intensity, while (VT) decrease with increasing illumination intensity. Finally the (C-V) characteristics was studied, the results showed that there are change in the capacity with change a voltage within range, out of this range the capacity fixed and the capacity of the device increases with increasing the frequency at same value of voltage.
