We study phonon-mediated adsorption and desorption of an electron at dielectric surfaces with deep polarization-induced surface potentials where multiphonon transitions are responsible for electron energy relaxation. Focusing on multiphonon processes due to the nonlinearity of the coupling between the external electron and the acoustic bulk phonon triggering the transitions between surface states, we calculate electron desorption times for graphite, MgO, CaO, Al{sub 2}O{sub 3}, and SiO{sub 2…

Influence of released surface electrons on the pre-ionization of helium barrier discharges: laser photodesorption experiment and 1D fluid simulation
The presented work highlights the role of residual weakly-bound surface electrons acting as an effective seed electron reservoir that favors the pre-ionization of diffuse barrier discharges (BDs). A
Influence of the voltage waveform during nanocomposite layer deposition by aerosol-assisted atmospheric pressure Townsend discharge
This work examines the growth dynamics of TiO2-SiO2 nanocomposite coatings in plane-to-plane Dielectric Barrier Discharges (DBDs) at atmospheric pressure operated in a Townsend regime using nebulized
Systematic investigation of the barrier discharge operation in helium, nitrogen, and mixtures: discharge development, formation and decay of surface charges
As a logical extension to previous investigations of the barrier discharge (BD) in helium and nitrogen, the present work reports on the operation in any mixtures of both pure gases. Using a
Surface charge transport and decay in dielectric barrier discharges
In this work, we investigate the decay of electric charge that remains after the extinction of a barrier discharge on top of a dielectric surface. The amount of surface charge is determined spatially
Novel insights into the development of barrier discharges by advanced volume and surface diagnostics
The comprehensive characterization of microdischarges (MDs) requires complementary diagnostics of volume and surface processes at the same discharge configuration under identical conditions. This
Surface charge accumulation and discharge development in diffuse and filamentary barrier discharges operating in He, N2 and mixtures
A new discharge cell configuration was developed which allows the joint investigation of important volume and surface processes of the barrier discharge (BD) operation. In particular, the
Electron kinetics at the plasma interface
Abstract The most fundamental response of an ionized gas to a macroscopic object is the formation of the plasma sheath. It is an electron depleted space charge region, adjacent to the object, which
Development of Barrier Discharges: Operation Modes and Structure Formation
A discharge cell configuration combining three high-end diagnostic techniques (cross-correlation spectroscopy, electro-optic Pockels effect and laser induced fluorescence spectroscopy) has been
Electron microphysics at plasma–solid interfaces
The most fundamental response of a solid to a plasma and vice versa is electric. An electric double layer forms with a solid-bound electron-rich region-the wall charge-and a plasma-bound
