Abstract

See full text

A semiconductor device comprises three semiconductor layers. The semiconductor layers are arranged to form a 2DHG and a 2DEG separated by a polarization layer. The device comprises a plurality of electrodes: first and second electrodes electrically connected to the 2DHG so that current can flow between them via the 2DHG and a third electrode electrically connected to the 2DEG so that when a positive voltage is applied to the third electrode, with respect to at least one of the other electrodes, the 2DEG and the 2DHG will be at least partially depleted.
