Reliability analysis of GaN-based UVLEDs under forward bias operations in salty vapor environment

摘要

We illustrated the reliability of longer wavelength ultraviolet light-emitting diodes (UVLEDs) in salty vapour environment under manipulation of forward-bias stress via consistent electrical and material characterizations. By manipulating the unprecedented operation in salty vapour ambient, we investigated a series of remarkable findings related to origin of failure behaviours.
