Figure 1From: Synthesis and characterization of aligned ZnO/BeO core/shell nanocable arrays on glass substrate SEM images of as-prepared ZnO nanowire arrays and ZnO/BeO nanocable arrays. (a) Plan-view and (b) cross-section SEM images of as-prepared ZnO nanowire arrays with HRTEM image of a single nanowire in the inset; (c) plan-view and (d) cross-section SEM images of ZnO/BeO nanocable arrays with Be 1s XPS spectra in the inset.Back to article page
