The effect of collisions, ionisation and non-extensivity is studied numerically in an electronegative warm plasma associated with electron emission from the wall. Electrostatic potential, space charge density, net negative charge density and emitted electron beam density are plotted with the normalised distance to see the effects of aforesaid parameters The negative ion is described with […]
AbstractBehaviour of sheath formed on two types of probes, namely cylindrical and spherical probes, has been investigated in terms of its thickness, in front of the conducting probes immersed in an electronegative plasma for different negative to positive ion mass ratios, by considering three electronegative gases, i.e. CF4, O2 and C60. Contrary to others’ work, […]
