ZnO-Microrod/p-GaN Heterostructured Whispering-Gallery-Mode Microlaser Diodes

ZnO-Microrod/p-GaN Heterostructured Whispering-Gallery-Mode Microlaser Diodes

The whispering gallery mode (WGM) lasing and microphotoluminescence from a hexagonal ZnO microrod are investigated. The hexagonal ZnO microrod is integrated on a p‐GaN substrate to fabricate a heterostructured microlaser diode and the electrically pumped WGM lasing from the diode is realized.
