摘要
ZnO is an important material which has been widely applied in photodetector, catalyst, gas sensor, field emitter, etc. Yet, its inability to absorb visible light, poor charge transport, and low conductivity limit the application of these devices. Recently, it was discovered that introduction of defects such as oxygen and zinc vacancies into ZnO can effectively improve the existing properties or lead to new and unexpected yet highly desirable characteristics. Herein, we present a systematic review on the available approaches to synthesize oxygen- and/or zinc-deficient ZnO with emphasis on their chemical, structural, and electrical particularities. Furthermore, applications of defective ZnO in various nanoscale devices are discussed in terms of their functionality, reliability, and performance. Finally, we summarize major challenges and offer perspectives for further research in this field. We hope that this review would make a valuable contribution to broaden the knowledge of defective ZnO.
