This paper focuses on understanding the influence of materials' properties on the ferroelectric electron emission. Ferroelectric (x=1.0 and 0.8) and paraelectric (x=0.67 and 0.5) compositions of barium strontium titanate (BaxSr(1-x)TiO3) system were chosen for study based on their different ferroelectric and dielectric properties. Similar emission current waveforms were obtained from four compositions with negative triggering voltage applied to the rear electrode of the samples. It was difficult to explain the experimental results using the spontaneous polarization-switching model. The mechanism of electron emission from BaxSr(1-x)TiO3 ceramics was ascertained to surface plasma emission.
