A Study on the Thermally Stimulated Current of PVDF Thin Film Prepared by Physical Vapor Deposition Method

진공증착법으로 제조한 PVDF 박막의 열자격전류에 관한 연구

The thermally stimulated current (TSC) of PVDF thin film prepared by physical vapor deposition method was investigated. PVDF shows three TSC peaks designated $P_1$, $P_2$ and $P_3$ in ascending order of temperature. The $P_1$ peak is associated with water in the PVDF specimen. $P_2$ and $P_3$ Peaks are specific peaks of $\alpha$ and $\beta$ type PVDF, respectively. The peak temperature was shifted to higher temperature, and peak intensity was decreased with increasing substrate temperature under thin film preparation.
