Chapter 16 Nanostructured ZnO Thin Films:Properties and Applications

摘要

Zinc oxide has been recognized as one of the most important semiconductor materials for optoelectronics, solar cells, piezoelectricity, gas sensing, bio- applications etc. ZnO has been an object of intensive investigation, particularly in its low dimensional structures - thin layers with nanometer crystallites, nano-wires, nano-rods or nano-tubes, nano-bells and others. In thi contribution the optical and structural properties of ZnO thin films are discussed. The application of ZnO thin films as a transparent conductive electrode for solar cells and light emitting diodes, as well as for gas sensors is demonstrated. The possibility for bio-application of ZnO films is also discussed.
