Fabrication and characterization of InGaN nano-scale dots for blue and green LED applications[Light Emitting Diodes]

Conference ·
OSTI ID:20104633
Thin layers of InGaN were grown by metalorganic chemical vapor deposition and characterized with atomic force microscopy and high-resolution transmission electron microscopy. InGaN deposited on GaN exhibits a Stranski-Krastanov growth mode, including 2D wetting layer and 3D self-assembled quantum dots. Besides, the authors observed that the formed InGaN nano-scale dots have a trapezoidal shape with a {l_brace}1--102{r_brace} facet with respect to (0002) surface. Visible spectral range from UV to green was easily obtained by changing InGaN quantum well thickness up to 2.3 nm.
