WebMay 2, 2024 · Conductivity transients with disperse decay kinetics and a first half-life of 2 ns were obtained in the temperature range from 210 to 450 K. The charge carrier mobility at high temperatures (T>300 K) is thermally activated (Ea=46 meV). A minimum for the sum of the charge carrier mobilities of holes and electrons was found to be 1×10−5 m2/Vs.
