Structures at the electrodes of gas discharges
Physical Review A, 1988A phenomenological model is developed to explain single spots or regular patterns of spots at the electrode of gas discharges. The electrodic discharge parts are described by bistable layers, governed by a time-dependent Ginsburg-Landau equation or reaction-diffusion equation; the space between the electrodic layers is taken into account by a resistive

We consider first the collisions of ions and electrons with the neutral atoms in a partially ionized plasma; collisions between charged particles are more complicated and will be treated later. Since neutral atoms have no external electric field, ions and electrons do not feel the presence of a neutral until they come within an atomic radius of it ...

Gas discharge in hexamethyldisiloxane
Journal of Applied Polymer Science, 1976A method of making thin polymer (polystyrene and polysiloxane) films by glow discharge is described. The thickness of the films varies between several hundred angstroms and a few microns. The parameters of the method are studied: pressure, frequency, current density in the discharge and discharge time.

Summary form only given. Potential relaxation oscillations in filament cathode discharges at very low pressure is examined by comparing experimental results from different discharge arrangements with particle-in-cell simulations and with a model based on the van-der-Pol equation. The filament cathode discharge has two stable modes of operation: the low-

Electrical Engineering, 1950
The microwave gas discharge has presented a new field for physical exploration. The r e sults of some of these experiments are given here; processes active in a microwave gas discharge are discussed, and a formula is developed for the complex conductivity of the discharge from the known properties of electrons and ions.

THE application of gas-phase glow discharges to the activation of many chemical reactions is becoming increasingly important but the parallel application to various aspects of the processing of materials is not as yet so well known. Dugdale1 has described the mechanism and characteristics of the d.c.
