shockley barrier layer
The barrier layer is positioned on the substrate.
Organic light-emitting-diodes by inserting C_(60) as exciton barrier layer
In AC electrical field, the stable homogeneous glow discharge will appear by using dielectric barrier layer and high-frequency power source.
Therefore, the barrier layer can prevent grinding fluid from infiltrating to the substrate during the polishing process, and further improve the effect and the quality of polishing and grinding.
