Excitation efficiency and limitations of the luminescence of Eu3+ ions in GaN
Dolf Timmerman, Brandon Mitchell, Shuhei Ichikawa +3
The excitation efficiency and external luminescence quantum efficiency of trivalent Eu3+ ions doped into gallium nitride (GaN) was studied under optical and electrical excitation.…

Investigation of electron beam induced migration of hydrogen in Mg-doped GaN using Eu as a probe
Brandon Mitchell, Donghwa Lee, Dong-gun Lee +3
We demonstrate the use of hydrogen induced changes in the emission of isoelectric Eu ions, in Mg-doped p-type GaN, as a powerful probe to study the dynamics of hydrogen movement un…
