Figure 2From: Synthesis and characterization of aligned ZnO/BeO core/shell nanocable arrays on glass substrate Images of ZnO nanowire arrays and ZnO/BeO nanocable arrays. SEM images of ZnO nanowire arrays synthesized of (a) 0.5 mmol zinc nitrate, (b) 1 mmol zinc nitrate, (c) 1.5 mmol zinc nitrate, and (d) 2 mmol zinc nitrate. Resulting ZnO/BeO nanocable arrays (e)-(h) using the ZnO nanowire templates as shown in (a)-(d).Back to article page
