| Research Abstract |
We propose to demonstrate nuclear spin imaging by means of single quantum dot spectroscopy. Since the photoluminescence spectral shift due to the nuclear effect is as small as10μeV, we built up ultra high-resolution spectrometers for this purpose. As a result we successfully observed fine-structure splits due to the electron-hole long-range interactions, their quantum dot size dependence, and their removal in highly-symmetric QDs which is newly grown by droplet epitaxy.
