  • Abstract
    An explanation is presented to account for discrepancies noted between donor densities determined by magnetoresistance and Hall measurements when high-resistivity layers are present in an epilayer-substrate composite. Experimental data on GaAs and InP samples show that net donor densities tend to reflect that of the most conducting portion of a Hall sample and the most resistive portion of a magnetoresistance sample.
