摘要：
Zinc oxide microwire lasers show whispering gallery mode lasing, exhibiting high Q-factors. The energetic positions of the lasing modes agree with those calculated from a simple plane wave model. The characteristic temperature of the microlasers was determined from temperature dependent measurements. Additionally, the authors demonstrate the successful growth of MgZnO/ZnO core-shell heterostructures by pulsed laser deposition.
