Abstract
One embodiment of the invention comprises a first semiconductor structure in electrical contact with a first contact region, a second semiconductor structure in electrical contact with a second contact region, the first semiconductor structure and the second semiconductor structure being in electrical contact with each-other along an interface, a modulating section configured to modulate the conductivity in at least one of the semiconductor structures, so that the conductivity varies along the interface, in such a way that if current flows across the interface, the current can flow only at a predetermined position along the interface, and substantially no current can flow at either side of the predetermined position.
