Abstract
Current-voltage and capacitance-voltage characteristics of polyvinyl alcohol (PVA) films with the inclusion of multi-walled carbon nanotubes (MWCNT) deposited on silicon and ITO substrates were experimentally studied. It is shown that such structures demonstrate rectifying properties and their current-voltage characteristics are nonlinear. With direct bias, the structures have a positive temperature coefficient of resistance (TCR). With a reverse bias, the sign of TCR changes from negative to positive. A qualitative analysis of the results based on the tunneling mechanism of current transfer is presented.
