Abstract:
1. A semiconductor heterobarrier electronic device comprising: a substrate; at least one pair of stacked layers comprising Group III-nitride semiconductor materials selected from the group of compounds consisting of GaN, InN, AlN, Al at least two electrical contacts operatively connected to the pairs of stacks; the first of the pair of stacked layers comprising layers that are Group III-polar and the second of the pair comprising layers that are N-polar, the pair of stacked layers being configured such that the spontaneous and/or piezoelectric polarization attributable to the arrangement of the atoms of the materials in first of the pair of stacked layers opposes the spontaneous and/or piezoelectric polarization attributable to the arrangement of the atoms of the materials in the second of pair of stacked layers; the first of the pair of stacked layers being spaced apart by a distance in the range of approximately 5 nm to 2 centimeters from the second of the pair of stacked layers; each of the pair of stacked layers ending with a Group III polar surface on one end and an N-polar surface on the opposite end, the at least two contacts being configured to connect the pair of stacked layers such one of the contacts interconnects the Group III-polar face of the first of the pair of stacked layers with the N-polar of the second of the pair such that the polarization charge is eliminated between the at least two contacts.
