At higher … dominate the electrostatic fluctuations experienced by the ion. At 360 K, close to the optimal growth temperature of …

Particles in Silicon Depositon Discharges

July 1, 2003
Author(s)
Alan Gallagher, G Bano, K Rozsa
In a radio frequency or high frequency discharge, electrons are accelerated toward the central plasma region by oscillating sheath electric fields. In a dc discharge, a cathode sheath field provides steady electron acceleration into the plasma. These
