| Abstract |
The purpose of this paper is to investigate the fabrication of P(VDF-TrFE) organic thin films through the vapor deposition method and the piezoelectric properties of the organic thin films thus produced. Vapor deposition was performed under the following conditions: the working temperature, and the pressure of reaction chamber were 300^{\circ}C, and 2.0×10^{-5} Torr, respectively. The molecular structure and crystallinity of the evaporated organic thin films were evaluated by using a FT-IR (Fourier-Transform Infrared spectroscopy) and XRD (X-ray diffractometry), The results showed that crystallinity increased with an increase in the substrate temperature. When the P(VDF-TrFE) organic thin films were fabricated by increasing the substrate temperature, its piezoelectric coefficient(d_{33}) increased. |
