Notes:
The emission of electrons from lead lanthanum zirconate titanate ceramics, showing ferroelectric or/and antiferroelectric properties at room temperature, after excitation by a rectangular high voltage electric pulse, is explained by the switching and relax-back of the spontaneous polarization. The reported simultaneous measurements of emitted and polarization switching pulses show clearly the expected correlation. From the shape of the switching current it is possible to foresee if the sample can emit or not. © 1998 American Institute of Physics.
