Figure 2From: Fabrication of ZnCoO nanowires and characterization of their magnetic propertiesFE-SEM images of ZnCoO nanowires fabricated using different ambient gases. (a) FE-SEM image of sample S1 obtained under continuous argon gas flow and (b) a magnified image. (c) FE-SEM image of sample S2 obtained under continuous air gas flow including oxygen and (d) a magnified image. (e) FE-SEM image of sample S3 obtained under initial air gas conditions without continuous air gas flow and (f) a magnified image.Back to article page
