AFM images, surface profiles, and histograms of nanoparticles diameter counted on surface areas for reference ZnO thin films [(a), (b), and (c)], as well as ZnO films with Au coverage obtained with 1200 [(d), (e), and (f)], 4600 [(g), (h), and (i)], and 9000 [(k), (l), and (m)] laser pulses.
Nanoparticles (a) average diameter and (b) average height as a function of number of laser pulses applied for the irradiation of the Au targets.
AFM images and conductivity maps of the same surface areas for reference ZnO film [(a) and (b)] and for ZnO films with Au coverage obtained with 1200 [(c) and (d)] as well as 9000 [(e) and (f)] laser pulses. The magnification is the same for all images and maps.
Local characteristics obtained in the center (continuous lines) and at the border (dashed lines) of the nanoparticles for a ZnO film with Au coverage obtained with 9000 laser pulses.
