Abstract
A configuration is disclosed. In one aspect, the configuration includes a substantially planar electrode layer, in a first plane. The configuration further includes a substantially planar two-dimensional electron gas (2DEG) layer electrically connected in series with the electrode layer. The 2DEG layer is provided in a second plane substantially parallel with the first plane and located at a predetermined distance, in a direction orthogonal to the first plane, from the first plane. The 2DEG layer and the electrode layer are patterned such that the electrode layer overlays a part of the 2DEG layer, wherein the predetermined distance between the first plane and the second plane is selected to be sufficiently small for allowing electrostatic interaction between the electrode layer and the 2DEG layer.
