- Abstract
- In this study, we have deposited the AlGaN thin films for distributdd Bragg reflector (DBR). We investigated effects of Al content (18.0% similar to 47.2%) and III/V ratio (1437 4792) on AlGaN thin film. We analyzed image of grown AlGaN epi-layer by FE-SEM. There are different growth behaviors depending on III/V ratio under the greatest Al contents. Therefore, we optimized the AlGaN epi-layer growth conditions that have the highest Al content and adjusted III/V ratio. Also, AlGaN thin films were analyzed. Finally, we fabricated DBR using optimized AlGaN epi-layer and characterized the optical properties and surface morphology.
