Determination of the velocity/field characteristic for n type indium phosphide from dipole-domain measurements

Measurements on dipole domains in indium phosphide have shown that the depletion ratio is low and varies with domain voltage for peak fields up to at least 75 kV/cm for material with a 6×1014 cm¿3 carrier density. A velocity/field characteristic, determined, using these data, has a much lower valley field than that indicated by previous measurements.
