Recent advances in surface charge dynamics in dielectric barrier discharge: future strategies for control and technological optimisation

Abstract Dielectric barrier discharges (DBDs) using atmospheric pressure plasma are utilised in various industries, including environmental remediation, semiconductor manufacturing, and energy technology. It is crucial to understand and regulate their properties for technological optimisation. Of particular significance is the surface charge generated by DBDs, as it is the primary physical factor that determines the electric field in the plasma, resulting in overcurrent suppression and radical formation. This study explores recent advancements in research concerning the dynamic properties of surface charge and examines future strategies for optimising DBDs and achieving real-time surface charge control.
