Current-voltage measurements with Schottky contacts in a planar back-to-back configuration have been performed for InAlN/AlN/GaN heterostructures with different AlN interlayer thicknesses. We have identified the onset of a 2-dimensional electron gas (2DEG) controlled conduction from current-voltage curves analyses.

The 2DEG properties extracted from current-voltage analyses have been compared with Hall measurements which shows excellent agreement in values.

Abstract

Current-voltage measurements with Schottky contacts in a planar back-to-back configuration have been performed for InAlN/AlN/GaN heterostructures with different AlN interlayer thicknesses. We have identified the onset of a 2-dimensional electron gas (2DEG) controlled conduction from current-voltage curves analyses. A model has been proposed to determine the 2DEG electrical properties and the effects of the AlN thickness on the measured current-voltage curves have been discussed. The 2DEG properties extracted from current-voltage analyses have been compared with Hall measurements which shows excellent agreement in values.
