Witryna8 kwi 2024 · Consequently, the impurity ions stir the enhancement of turbulence and turbulent transport owing to the reduced GAM zonal flow as demonstrated in the experiment. These experimental results presented here therefore reveal the dual roles played by impurity ions on the dynamics of GAM zonal flows. In quantum mechanics, ionized impurity scattering is the scattering of charge carriers by ionization in the lattice. The most primitive models can be conceptually understood as a particle responding to unbalanced local charge that arises near a crystal impurity; similar to an electron encountering an electric field. This effect is the mechanism by which doping decreases mobility. In the current quantum mechanical picture of conductivity the ease with which electrons traverse a crystal … simple topographic map examples
