Field emission characteristics of three different ferroelectric cathode materials: lead zirconate titanate( PZT), natrium bismuthate titanate( BNBT) and barium titanate( BT) were experimentally studied and their emission waveforms were analyzed.

• 本文采用锆钛酸铅、酸铋钠和钛酸钡三种不同铁电阴极材料,进行了电子发射试验,测定了电子发射电流密度,并对其在电子发射试验时的波形进行了分析讨论。
