Liangzhi Kou, Chun Li, Zi-Yue Zhang, Changfeng Chen, and Wanlin Guo We predict by first-principles calculations a spontaneous charge carrier separation mechanism in pristine [0001]-oriented ZnO nanowires. We find that the shrinking strain induced by surface reconstruction causes electrons and holes to separate and move toward the core and surface region, respectivel ... [Appl. Phys.
