Effect of annealing on electron dephasing in three-dimensional polycrystalline metals
Effect of annealing on electron dephasing in three-dimensional polycrystalline metals
We have studied the effect of thermal annealing on electron dephasing times $\tau_\phi$ in three-dimensional polycrystalline metals. Measurements are performed on as-sputtered and annealed AuPd and Sb thick films, using weak-localization method. In all samples, we find that $\tau_\phi$ possesses an extremely weak temperature dependence as $T \to 0$. Our …
