Influence of pulse polarity on electron emission property of antiferroelectric ceramic

Electron emission from La-doped Pb(Zr,Sn,Ti)O3 anti-ferroelectrics by pulse electric field and the relevant physical mechanism

“…This result made it possible to study the field-induced phase transition at room temperature [10] . By adjusting the components near the antiferroelectric-ferroelectric phase boundary, PLZST ceramics with a large emission current was obtained [11] . In this article, we report the results from a series of experiments recently performed to understand the effect of triggering pulse polarity and extraction voltage on the electron emission behaviors of the ferroelectric cathodes.…”
