Nanobelts,Nanowires, and Nanodiskettes of Semiconducting Oxides—From Materials to Nanodevices

Novel nanostructures of semiconducting oxides are reviewed here. It is shown that nanobelts, nanowires, and nanodiskettes of materials such as zinc oxide, gallium oxide, silica, and tin oxide can be fabricated using a vapor‐phase evaporation method. Two applications of these materials—in field effect transistors and as gas sensors—are highlighted.
