[交流] ZnO based nanowires

Title: ZnO based nanowires
Author：S. J. PEARTON, Department of Materials Science and Engineering University of Florida
Journal：NANO: Brief Reports and Reviews Vol. 2, No. 4 (2007) 201–211 World Scientiﬁc Publishing Company

Abstract: ZnO has properties well-suited to UV/visible light emitters, transparent thin ﬁlm electronics and
a variety of gas and chemical sensor applications. There has been extensive interest in recent
times in synthesis of ZnO nanowires by a number of methods using both catalyst and catalyst-free
approaches. In this paper we review our recent results on developing functional nanowires in the
ZnMgO systems and show some applications in hydrogen gas sensing, pH sensing, transparent
transistors and UV detectors. In terms of sensors, the main selling points are large surface-to-
volume ratio for improved detection sensitivity and also low power requirements.
