| 제목 | Nanoscopic InGaN/GaN Quantum Structures for Visible Wavelength Tunability |
| 초록 | InGaN-based light emitters often suffer from the lack of wide-range wavelength controllability, particularly in the green and yellow region. the origin of this drawback arise mainly from the difficulty for In atoms to be incorporated and the significant internal electric field between the quantum wells and barriers on the polar plane. Due to increasing demand to extend the emission wavelength into the longer regime, there has been tremendous efforts to overcome this limitation. Nanostructrued InGaN/GaN quantum structures on the semi-polar or non-polar plane can be considered to be a promising solution for large-area high efficiency InGaN-based light emitters with the wide emission wavelength. Here, we report the growth and characterization of nano-pyramid structures embedding the mulitple InGaN/GaN quantum structures and investigates the possibility to tune the emission wavelength from blue to yellow regime. Therefore, our results indicate that the adoption of nano-pyramid structures and relevant optimized growth conditions will enable the while emission of InGaN/GaN quantum structures as well as the wide visible wavelength tunability. |
