Hollow cathode
NettetThe authors report on the use of hollow cathode plasma for low-temperature plasma-assisted atomic layer deposition (PA-ALD) of crystalline AlN, GaN and AlxGa1−xN thin films with low impurity concentrations. Depositions were carried out at 200 °C using trimethylmetal precursors and NH3 or N2/H2 plasma.
