The micro photoluminescence (PL) and micro time-resolved PL spectroscopy have been performed on a single InGaN/GaN nanocolumn structure grown by nitrogen plasma assisted molecular beam epitaxy. The PL spectra of single InGaN/GaN nanocolumn consist of about tens sharp emission peaks, which position does not change even if the photo-excitation carrier density increases, unlike the conventional c-plane InGaN/GaN quantum well structures (QWs). Moreover, the PL lifetime of InGaN/GaN nanocolumn is two orders of magnitude faster than that taken at the same wavelength in conventional InGaN/GaN QWs. These results suggest that the piezoelectric polarization field is suppressed in InGaN/GaN nanocolumn, and the small localized centers are formed in InGaN/GaN nanocolumn. |
