Abstract

The intrinsic Rashba field in an InAs quantum well is observed using a potentiometric geometry in which a circular shaped permalloy electrode is utilized with a rotational applied field. From the ratio of the curve shift to the applied field and the amplitude of potentiometric signal, a Rashba field of 8.84 T can be estimated. This method is a very simple and accurate alternative to quantitatively observe the Rashba field.
