Thin VDF-TrFE copolymer films of molar composition 70/30 and thickness from 25 nm to 175 nm have been prepared by spin coating on a glass substrate covered with an aluminum electrode. The linear, second and third order permittivities &#x03B5;<sub>1</sub>, &#x03B5;<sub>2</sub> and &#x03B5;<sub>3</sub> of poled and unpoled samples have been studied versus(More)
VDF-TrFE copolymer thin film of molar composition 70/30 and thickness below 70 nm has been prepared by spin coating on glass substrate covered with aluminum electrode. After polarization at room temperature by some hysteresis cycles, the linear and second order permittivities &#x03B5;<inf>1</inf> and &#x03B5;<inf>2</inf> have been studied over temperature(More)
