Atomic Layer Deposition of \(Sc_2O_3\) for Passivating AlGaN/GaN High Electron Mobility Transistor Devices
(American Institute of Physics, 2012)Polycrystalline, partially epitaxial \(Sc_2O_3\) films were grown on AlGaN/GaN substrates by atomic layer deposition (ALD). With this ALD \(Sc_2O_3\) film as the insulator layer, the \(Sc_2O_3\)/AlGaN/GaN metal-insulator- ... -
Thermionic Emission and a Novel Electron Collector in a Liquid Helium Environment
(American Institute of Physics, 2009)We study two techniques to create electrons in a liquid helium environment. One is thermionic emission of tungsten filaments in a low temperature cell in the vapor phase with a superfluid helium film covering all surfaces; ...
