- 論文の詳細を見る
Luminescence from single isoelectronic traps in nitrogen $\delta$-doped gallium phosphide was studied by micro-photoluminescence spectroscopy. These single traps were found to emit photons that were nearly identical in both emission energy and brightness. Furthermore, single photon emission from a single nitrogen pair is confirmed by a strong antibunching under continuous optical excitation at 30 K. These results imply that single nitrogen pairs in GaP might be useful for realizing unique sources of energetically-defined single photons, and even indistinguishable photons.
