Abstract:ZnO nanoribbons with zigzag edges and ultrafine nanowire-like tips (diameter about 10 nun) were synthesized via a facile method at a relatively low temperature without any catalysts or templates. The nanoribbons are about 30 urn in thickness, 500 nut in length, and tapered in width. It is hydrogen peroxide that results in the formation of ZnO nanoribbons with zigzag edges. As an oxidant, hydrogen peroxide provides not only oxygen for the growth of ZnO nanoribbons but also water vapor for impeding the growth of the nanoribbons along 100011 and accelerating the <01<(1)over bar>0> growth of ZnO nanoribbons. Bottom-gate ZnO-nanoribbon-based field-effect transistors demonstrated n-type 10..e.c.-e...ect conduction, and the current on-to-off ratio was as high as 1 x 10(4). The novel method developed in this study can be used to synthesize other metal Oxides with zigzag
