Title: Strong electron emission from antiferroelectric PLZT(2/95/5) films

Strong emission current of 500 mA/cm{sup 2} was observed in sol-gel derived antiferroelectric (AFE) PLZT (2/95/5) thick films at a trigger voltage of 150 V and a dc extraction voltage of 50 V. The PLZT emitters were found to be fatigue-free up to 10{sup 6} emission cycles. Electron emission from our samples is believed to originate from the antiferroelectric-ferroelectric phase transition in the PLZT film emitters. Our results therefore indicate that PLZT could be a promising candidate for flat panel applications because of its higher saturated polarization and fatigue-free properties as compared to its ferroelectric counterparts.
