Nonradiative quenching of EPR signals in germanium-doped AlGaN: evidence for DX-center formation

Jason Forbus, Darshana Wickramaratne, John L. Lyons +1

We present photo-electron paramagnetic resonance (EPR) measurements and first-principles calculations that indicate germanium (Ge) is a DX-center in AlGaN. Our photo-EPR measuremen…
