Ultrathin single-crystal ZnO nanobelts : Ag-catalyzed growth and field emission property
We report the growth of ultrathin single-crystal ZnO nanobelts by using a Ag-catalyzed vapor transport method. Extensive transmission electron microscopy and atomic force microscopy measurements reveal that the thickness of the ultrathin ZnO nanobelts is ∼2 nm. Scanning electron microscopy and po...

| description | We report the growth of ultrathin single-crystal ZnO nanobelts by using a Ag-catalyzed vapor transport method. Extensive transmission electron microscopy and atomic force microscopy
measurements reveal that the thickness of the ultrathin ZnO nanobelts is ∼2 nm. Scanning electron microscopy and post-growth annealing studies suggest a ‘1D branching and 2D filling’ growth process. Our results demonstrate the critical role of catalyst in the deterministic synthesis of nanomaterials with the desired morphology. In addition, these ultrafine nanobelts
exhibit stable field emission with unprecedented high emission current density of 40.17 mA cm−2. These bottom-up building blocks of ultrathin ZnO nanobelts may facilitate the construction of advanced electronic and photonic nanodevices. |
