This study investigates the enhancement of surface charge, electric field, and afterglow in non-equilibrium plasma using a ferroelectric barrier discharge (FBD) with Pb(ZrₓTi₁₋ₓ)O₃ (PZT) electrodes. The results show that FBD significantly increases surface charge by two orders of magnitude compared to dielectric barrier discharge (DBD) with alumina barriers. Time-resolved in-situ electric field measurements reveal that the fast polarization of ferroelectrics enhances the electric field during breakdown in streamer discharge, doubling it compared to DBD. Additionally, the ferroelectric electrode extends the afterglow time and makes the discharge more sustained when alternating the external electric field polarity. The study demonstrates that FBD offers a promising technique to tune plasma properties for efficient plasma catalysis and electrified manufacturing. The enhanced electric field and sustained afterglow are attributed to the spontaneous electric polarization of ferroelectrics, which increases surface charge and sustain reactive species. The findings highlight the potential of FBD for applications in plasma catalysis and material synthesis.This study investigates the enhancement of surface charge, electric field, and afterglow in non-equilibrium plasma using a ferroelectric barrier discharge (FBD) with Pb(ZrₓTi₁₋ₓ)O₃ (PZT) electrodes.
