Electron heating in radio-frequency capacitively coupled atmospheric-pressure plasmas

In atmospheric-pressure plasmas the main electron heating mechanism is Ohmic heating, which has distinct spatial and temporal evolutions in the α and γ modes. In γ discharges, ionizing avalanches in the sheaths are initiated not only by secondary electrons but also by metastable pooling reactions. I...
