| Abstract: | The switching characteristics of ferroelectric thin films and the measurement of relevant parameters are discussed. The bipolar double pulse generator, an important instrument for measuring the switching characteristics of ferroelectric thin films, and the principle of the hysteresis loop measurement with the bipolar double pulse are described. The hysteresis loop measured is more dependable than that measured with conventional methods. Besides, the reversal of polarization of ferroelectric thin films can also be seen. |
