[20p-P13-14] Hall factor for nearest-neighbor hopping conduction in Mn-doped GaAs
Keywords:nearest-neibor hopping conduction,impurity-band conduction,Hall factor
The experimental data of the Hall-effect measurements on Mn-doped GaAs have been analyzed with assuming that the Hall factor for nearest-neibor hopping conduction depends on temperature as Aib=(kBT/J)exp(T0H/T). As a result, the acceptor concentrations obtained in the conventional analysis have been proved to be larger than the true values by several ten times.
