In this paper, polymethylmetacrylate (PMMA) films are modified using an atmospheric pressure non-thermal plasma generated by a dielectric barrier discharge (DBD) in air. The DBD is generated in a plane-parallel reactor, which is driven by a μs pulse power supply with amplitude of up to 25 kV and repetition rate of 1 kHz, and the plasma generated shows homogeneous mode discharge characteristics verified...
Amorphous CoNbZr alloys are thermally stable and thus have been intensively studied as soft layers of a pseudo-spin-valve (PSV). By depositing a wedge-shaped Co inset layer (IL) between the CoNbZr and Cu layer, we were able to simultaneously fabricate CoNbZr(t CNZ )/Co(0–3nm)/Cu/Co PSVs with various CoNbZr and Co IL thicknesses. We have investigated the dependence of magnetic properties, giant...
A sheath model in an oblique magnetic field is build, which has one-dimension coordinate space and three-dimension speed space. The effects of magnetic field on the structure of RF sheath and parameter characteristics are discussed. The numerical simulation result shows that magnetic field has great effects on the sheath structure, especially in the region near the edge of sheath. Also, the magnetic...
A pulsed voltage of magnetically insulated diode and intense pulsed ion beam (IPIB) models have been built according to the experimental results. A model of secondary electrons yield while IPIB irradiated metal target has also been established. The temporal law of secondary electrons induced by IPIB irradiated titanium target according to the energy deposition at surface layer has been calculated...
The characteristic of dust plasma sheath in an oblique magnetic field was studied using the fluid method. In a magnetic field of various magnitude and directions, the charged dust density distribution has been discussed. It is shown that magnetic field does have effect on the dust characteristic. The action of electrostatic, gravitational force and Lorentz force make the dust grains do a helical movement...
The structure of the plasma sheath in an oblique magnetic field with the fluid method was investigated. In various magnitude and directions of the magnetic field, the electron and ion density distribution, ion flow velocity, electron potential and Bohm's criterion have been calculated. It is shown that magnetic field has obvious effect on the plasma sheath. Under the action of electrostatic and Lorentz...
For small and dense dusts, using the fluid model, the distribution and suspension of dust particles under the action of electrostatic, gravitational and ion-drag forces are investigated in the plasma sheath. It is shown that competition among the forces results in spatial oscillations of the particle distribution. However, for large and rare dusts using the isolated particle model the suspension of...
