Single Crystal SnO_2 Zigzag Nanobelts

摘要

Research on the growth and properties of nanobelt-based materials has increased steadily since their discovery,largely due to their potential applications in nanoscale devices as interconnects or functional components.A variety of nanobelts have been fabricated for a wide range of materials,such as semiconductors and oxides.Very recently,it has been shown that several new geometric configurations,such as nanohelices5 and nanorings,6 can be grown from nanobelts.SnO_2 is an environmentally friendly semiconductor with the band gap of 3.6 eV at room temperature.It has attracted a lot of interest as an excellent candidate for photoluminescence material and gas sensor.Many efforts have been made on the preparation and application of SnO_2 nanobelt-based materials.In this study,we present a peculiar microstructure of nanobelt-based SnO_2,zigzag structure,which was prepared by oxidizing Sn at high temperature.
