Abstract
We demonstrated light confinement in hexagonal GaN nanodisks. The nanodisks were fabricated by crystal growth via radio-frequency plasma-assisted molecular beam epitaxy, and the side length of the nanodisks was approximately 300 nm. Sharp peaks appeared at a wavelength of approximately 370 nm in the room-temperature photoluminescence spectrum of the nanodisks, indicating that the nanodisks acted as an optical nanoresonator. In addition, the results obtained by a finite-difference time domain method suggest that the resonant mode acting preferentially in such nanodisks is the whispering gallery mode. These results indicate that the GaN-based simple nanostructures can be used for nanolasers.
