| Outline of Final Research Achievements |
Praseodymium (Pr) doped GaN has the potential to be "single photon source" which is used for basic technology of quantum telecommunication. In this study, high concentration Pr doping into a microscopic region (1um x 1um x 50nm) on GaN was realized by using photolithography, ion implantation, and high temperature annealing techniques. Also, photoluminescence from Pr ions in the microscopic region was successfully observed with high-contrast by a high precision confocal microscopy at room temperature. We conclude that by father improving nano-patterning technique, activation of Pr ions, and sensitivity of the confocal microscope, the single photon emission from single Pr ions could be observed and controlled at room temperature.
