Abstract
Electrical glow discharge technique was employed for the preparation of plasma polymerized vinylene carbonate (PPVC) thin films of aluminum/thin film/aluminum sandwich structure at room temperature by a parallel plate capacitively coupled reactor. The structural investigation of the monomer VC and PPVC was performed by Fourier transform infrared spectroscopy. The current density-voltage characteristics follow a power law of the form J α V n, where n has different values. In the low voltage region 0.85 < n < 1.00 and those in the high voltage region lie between 1.30 < n < 1.75, indicating Ohmic current conduction in the low voltage region and non-Ohmic conduction in the high voltage region. In addition, at higher temperature the current density increased significantly revealing a temperature dependence of the current density. Theoretically calculated values and experimental results of Schottky and Poole-Frenkel coefficients show that the most probable conduction mechanism in the PPVC thin films is of Schottky type.
