From: Internal stress induced natural self-chemisorption of ZnO nanostructured films
Top view FE-SEM images for the ZnO nanostructured films (a) Z125, (b) Z150 and (c) Z175, respectively. (d–f) show the grain size histograms for evaluating average size and its distribution of the samples Z125, Z150 and Z175, respectively. (g–i) are the corresponding CA images for the samples Z125, Z150 and Z175, respectively.
