Reduction of Band-Gap Energy in GaNAs and AlGaNAs Synthesized by N+ Implantation

Shan, Wei; Yu, Kin Man; Walukiewicz, W; Ager, J W; Haller, E E; Ridgway, Mark C


The optical properties of nitrogen implanted GaAs and AlGaAs were investigated. The change in band-gap energy in the implanted region was analyzed using photomodulation spectroscopy. Results showed that by increasing N+ implantation dosage, the fundamental band-gap energy decreases.
