Tuning of the optical properties of In-rich InxGa1−xN (x=0.82−0.49) alloys by light-ion irradiation at low energy

Tuning of the optical properties of In-rich InxGa1−xN (x=0.82−0.49) alloys by light-ion irradiation at low energy

The effects of low-energy irradiation by light ions (H and He) on the properties of In-rich InxGa1−xN alloys are investigated by optical and structural techniques. H-irradiation gives rise to a remarkable blue-shift of light emission and absorption edge energies. X-ray absorption measurements and fi...

Zusammenfassung:The effects of low-energy irradiation by light ions (H and He) on the properties of In-rich InxGa1−xN alloys are investigated by optical and structural techniques. H-irradiation gives rise to a remarkable blue-shift of light emission and absorption edge energies. X-ray absorption measurements and first-principle calculations address the microscopic origin of these effects.
