Plasma polymerization (or glow discharge polymerization) uses plasma sources to generate a gas discharge that provides energy to activate or fragment gaseous or liquid monomer, often containing a vinyl group, in order to initiate polymerization.
Swann attending to his original prototype glow discharge equipment in the laboratory at STL Harlow, Essex in the 1960s. It represented a breakthrough in the deposition of thin films of amorphous silicon, silicon nitride, silicon dioxide at temperatures significantly lower than that deposited by pyrolytic chemistry.
The simplest type of glow discharge is a direct-current glow discharge. In its simplest form, it consists of two electrodes in a cell held at low pressure (0.1–10 torr; about 1/10000 to 1/100 of atmospheric pressure).
Plasma etching is a form of plasma processing used to fabricate integrated circuits.It involves a high-speed stream of glow discharge of an appropriate gas mixture being shot (in pulses) at a sample.
Glow-discharge optical emission spectroscopy (GDOES) is a spectroscopic method for the quantitative analysis of metals and other non-metallic solids. The idea was published and patented in 1968 by Werner Grimm from Hanau, Germany .
A glow discharge is a plasma-containing apparatus in which the plasma is formed by a large voltage placed across a rarefied gas. Glow discharges are used for electric lighting and materials processing. In a glow discharge, ionization instability takes the form of striations, [1] or bands of enhanced and suppressed light production. The distance ...
The A-D region is called a dark discharge; there is some ionization, but the current is below 10 microamperes and there is no significant amount of radiation produced. The F-H region is a region of glow discharge; the plasma emits a faint glow that occupies almost all the volume of the tube; most of the light is emitted by excited neutral atoms.
Nitrogen glow Oxygen glow Electrical discharge in air Particle beam from a cyclotron. Ionized-air glow is the luminescent emission of characteristic blue–purple–violet light, often of a color called electric blue, by air subjected to an energy flux either directly or indirectly from solar radiation.
