Abstract
The value for the GaAs electron effective mass as deduced from Zeeman splittings of the donor levels is strongly field dependent for weak magnetic fields. This behavior can be understood quantitatively as a consequence of the Stark perturbation of these levels due to random static electric fields present throughout the semiconductor. From the magnetic field dependence of the Zeeman effective mass we estimate the electric field strength in the sample.
