Abstract
The electron Hall mobility in InSb has been measured at 200∼430 K by van der Pauw's method. The experimental data were compared with theoretical values calculated by an iteration technique with a variable parameter |El|. In the calculations, the temperature dependence of m* was estimated from the experimental data of Eg(T) and m*(0) on the basis of Ravich's theory, and the value of κs was taken to be 16.8 instead of κs∼17.5. The comparison between the theoretical and experimental values of µH led to the value of |El|=33 eV, which is more than two times larger than that obtained in a previous work.
