Record negative photoconductivity in N-polar AlGaN/GaN quantum-well heterostructures

Maciej Matys, Atsushi Yamada, Toshihiro Ohki +1

The AlGaN/GaN quantum-well heterostructures typically exhibit a positive photoconductivity (PPC) during the light illumination. Surprisingly, we found that introducing the GaN/AlN…
