| Research Abstract |
This study established the method(s) of preparing ZnO/GaN-based hybrid microcavities. Specifically, crack-free ZnO/GaN hybrid microcavities were found to be well prepared with the MOCVD, MBE and UHCVD methods, and the GaN microcavities, with the MOCVD method using epitaxial lateral overgrowth technique. Fundamental optical properties for these microcavities, such as strong coupling regime, were characterized by the angle-resolved reflectivity and photoluminescence measurements. Unfortunately, no coherent phonon was generated from those microcavities, and its relationship with the cavity polariton remained unclear. Further study is planned for this relationship.
