| Popis: | Pulse electric-field-induced electron emissions from Pb-based ferroelectrics, antiferroelectrics, and paraelectrics were investigated. The electron emission charge increased exponentially with applied pulse field regardless of the dielectric phases. Electrons were emitted at the falling point as well as at the rising point of an applied pulse field when the antiferroelectrics and paraelectrics were used. The variation of emission charge from antiferroelectrics and paraelectrics was similar to that from ferroelectrics, as the emission charge increased exponentially with the polarization change [Ps-(−Pr)]. |
