Va. Godyak et Vi. Kolobov, EFFECT OF COLLISIONLESS HEATING ON ELECTRON-ENERGY DISTRIBUTION IN ANINDUCTIVELY-COUPLED PLASMA, Physical review letters, 81(2), 1998, pp. 369-372
Significant frequency dependence of the electron energy distribution h
as been found in a low-pressure inductive discharge experiment. The ob
served frequency dependence reveals The presence of collisionless elec
tron heating and appears as a result of finite electron-transit time t
hrough the skin layer. The energy distributions;calculated from a kine
tic equation accounting for nonlocality of electron kinetics and elect
rodynamics are in good agreement with the experiment.
