Deskripsi
We show the ferroelectric switching of a thin film of the copolymer of 60 mol% vinylidene fluoride and 40 mol% trifluoroethylene when it is subjected to a sinusoidal electric field from 10 Hz to 100 kHz using a conductive probe chip of AFM. A switching speed of 1.6 ×106 s-1 (switching time of 660 ns) was measured at 100 kHz switching.
