摘要：

For the first time a contactless method based on the Pockels effect is used to determine the spatial potential distribution in the two-dimensional electron gas of a GaAs/AlxGa1-xAs heterostructure under quantum Hall conditions. From first results we deduce that in the two-dimensional electron gas structure edge currents as well as currents in the interior are present. © 1990.
