Observation of sharp emission lines in the photoluminescence spectrum of a Zn doped GaN Quantum well

摘要

Ⅲ-Nitride materials are finding much use in the realization of several solid state light emittingdevices such as high-performance lasers with low threshold current, and, of course, LEDs.Furthermore, quantum sources of light, such as single photon emitters, are currently being heavilyresearched. To date, Ⅲ-nitride QDs have been studied for such single photon emission, but otherpossible sources of Ⅲ-nitride based quantized emission have so far received little attention. Here,we report our attempts to isolate the emission from a single Zn dopant based emission center in GaNfor single photon emission in the blue visible region of the electromagnetic spectrum.
