Three-dimensional photoluminescence imaging of threading dislocations in GaN by sub-band optical excitation

Three-dimensional photoluminescence imaging of threading dislocations in GaN by sub-band optical excitation

Abstract GaN is rapidly gaining attention for implementation in power electronics but is still impacted by its high density of threading dislocations (TDs), which have been shown to facilitate current leakage through devices limiting their performance and reliability. Here, we discuss a novel implem...
