Abstract(in English) | The growth and optical properties of GaN-based quantum dots (QDs) have been investigated. The lasers with GaN-based QDs embedded in the active layer are expected to have the superior characteristics such as lower threshold current densities at short wavelength. First, InGaN self-assembled QDs are demonstrated. The lateral size of InGaN QDs was as small as 10-nm-scale and the intense photoluminescence was observed at room temperature. For laser applications, the structure with InGaN QDs embedded in the active layer was fabricated. A clear threshold was observed in the dependence of the excitation intensity at room temperature under optical excitation. Second, selective growth of InGaN QDs is demonstrated to improve the uniformity of QDs. |
