Outline of Final Research Achievements

This work demonstrated the single photon emission from a single nitrogen impurity center in AlAs. The results allow for realizing visible quantum light sources on GaAs substrates. Theoretical calculation revealed the emission originating from nitrogen pairs in the nearest neighbor configuration. The nitrogen doped AlGaAs provided intense luminescence in the wavelength range from visible to near infrared.
