Temperature-dependent electrical characteristics of neutron-irradiated GaN Schottky barrier diodes

Min Zhu et al.

Summary: The study explicitly investigated the temperature-dependent electrical characteristics of a neutron-irradiated GaN SBD, revealing a decrease in electron concentration and Schottky barrier height inhomogeneity due to neutron irradiation. Although a new deep-level trap was identified, the results specified the outstanding resistance to neutron irradiation and robustness in extreme operation temperatures of the GaN SBD.

Impact of high-dose gamma-ray irradiation on electrical characteristics of N-polar and Ga-polar GaN p-n diodes

F. Mirkhosravi et al.

Summary: The impact of high-dose gamma-ray irradiation on Ga-polar and N-polar GaN-based p-n diodes grown by metalorganic chemical vapor deposition was investigated. Changes in electrical characteristics after irradiation were found to be temporary, potentially due to the metastable occupancy of traps. Different types of initial defects and surface electronic states were identified on Ga-polar and N-polar samples, providing insight into the different electrical behavior observed after gamma-ray interactions.

Reducing the reverse leakage current of AlGaN/GaN heterostructures via low-fluence neutron irradiation

Rong Wang et al.

Summary: Low-fluence neutron irradiation is a promising way to reduce the reverse leakage current in AlGaN/GaN heterostructures while maintaining other electronic properties almost unchanged. The mechanism involves the mobility of neutron scattered group-III interstitials, passivation of V-III-DLs, and escape of interstitials after saturation of passivation. This post-processing treatment offers a new approach for improving the electronic properties of AlGaN/GaN heterostructures grown by MOCVD on sapphire substrates.
