To obtain the hysteresis loops of ferroelectric capacitors, two cycles of triangular voltage profile were applied to a 100 μm × 100 μm capacitor. The hysteresis switching current and time were measured and recorded immediately using this system. Using integral calculus to convert switching current to charge, the polarization-
voltage (P-V) curve can be determined. Additionally, the hysteresis loop of the 100 μm × 100 μm capacitor was also measured using a standardized ferroelectric test system RT66A in the virtual ground mode (VGM) to verify the P-V curve. 7-3. Results and Discussions The experimental procedures were mentioned in the previous section.
In the hysteresis loop measurement, In pulse sequence to the same architecture of the shunt method. For the CC and TC methods, a constant charging current and a triangular charging current are applied to a specimen and the resulting voltage profiles are recorded simultaneously, to determine its hysteresis loops.
It was found that ferroelectric hysteresis loops of PZT capacitor measured at different temperature are virtually the same and that only a reduced coercive voltage exhibits in the corrected P-V curves as measurement temperature increased. (b) full-switching characteristic.
As the basic characterization for ferroelectric material, hysteresis loop measurement based on Sawyer-Tower circuit has restrictions of electrodes, parallel plate capacitor structure and complex compensating circuit, which cannot satisfy the demand for characterization of small dimensional ferroelectric materials.
Additionally, in the shunt method, the sensing capacitor is replaced with a reference resistor ( R ) in the switching current measurement . In the hysteresis loop measurement, In pulse sequence to the same architecture of the shunt method.
