Impurity density
Witryna18 maj 2024 · Not only can impurities have dominant components of neoclassical transport in addition to the turbulent transport, but also high mass and charge open the possibility of impurity density distributions which are not poloidally homogeneous on the magnetic flux surfaces, providing additional complexity to the problem. WitrynaAbstract: Threshold voltage shift of GaN MOSFET in positive bias temperature instability test was drastically suppressed by reducing certain impurity densities in SiO 2 gate dielectric. An analysis to estimate the charge trap level showed electron traps in the gate dielectric caused the threshold voltage shift in GaN MOSFETs.
