The low-temperature transport properties of front-gated Al 0.18Ga0.82N/GaN heterostructures were investigated. The carrier density showed a linear dependence on the applied gate voltage, consistent with a simple parallel-plate capacitor model. The average distance between the GaN electron system and the AlGaN/GaN interface was estimated to be 240 Å.
