Web20 apr. 2024 · Therefore, the ion impurity scattering becomes the dominant influence on mobility in both single-crystal samples and polycrystalline samples. This is because the electrons move more slowly in the low-temperature range, so the decreased momentum of the electrons allows them to be deflected by Coulomb force from the impurity ions. Web22 aug. 2024 · In addition, the impurity cases in figure 1 (shown with the blue solid lines where for L ez = −2) and 2 (shown with the blue dotted lines where for L ez = 1) together show that for the cases without ion temperature gradient but with sufficient fraction of impurity ions, regardless of the direction of impurity density peaking, i.e., both for L ez …
