Analysis of Electrical and Capacitance-Voltage of PVA/nSi

The present study examined polyvinyl alcohol, PVA, in its pure form without any additives. We investigated its application as a Schottky barrier device, which demonstrates the novelty of this research. We report the synthesis, current-voltage (I-V) and capacitance-voltage (C-V) characteristics, dielectric properties, x-ray diffraction of PVA/nSi. Several parameters, including the ideality factor (n), series resistance (R-s), barrier height (Phi(b)), the saturation current (I-0), and shunt resistance (R-sh) were estimated. It was found that the n values decrease with increasing temperature, setting the enhancement of the device features. (Phi(b)) values tend to increase with temperature rise. Frequency, voltage and temperature dependence of electric modulus ((M'& M '') was investigated, showing that (M') decreases with temperature (T) while the values of (M') are increased with frequency (f). But at low frequencies (M') rises when T is raised: While (M '') tends to be reduced with increasing T at (f) = 10 and 10(3) Hz, with increases at (f) = 2 x 10(7) Hz. We observed semicircles in the Cole-Cole plots where the radii of curvature increased with temperature and voltage.
