“…A probable reason is that the grain size measured from AFM is the surface morphology of coalesced grains which gives the particle size, the other reason for that is the effects of AFM tip‐shape. T. Kumpika et al suggested that the mean size of grain is prepared from the conical tip, which was larger than the sharp tip . Nevertheless, it can be seen from Fig.…”

Highly C-axis oriented ZnO thin film was manufactured by radio-frequency magnetron sputtering technique on Si (111) substrate. The main objective was to study the influence of rapid thermal annealing (RTA) temperature on the structure and interfacial characteristic of ZnO thin films. X-ray diffraction results showed that the ZnO thin films annealed at 600 C by RTA technique had a perfect C-axis preferred orientation compared to the other ZnO thin films, and the full width at half maximum of ZnO (002) rocking curve measurements indicted that the RTA-annealed ZnO thin films possessed better crystal structure. Atom force microscopy displayed that the grain size of RTA-annealed ZnO thin films was fine and uniform compared with the as-deposited ZnO thin films, although the grains grew in RTA process and the root meant square roughness was smaller than that of as-deposited films. High-resolution transmission electron microscopy showed that there was an obvious amorphous layer between ZnO thin films and Si substrate, but the RTA-annealed ZnO thin films exhibited larger and denser columnar structure and a preferred orientation with highly c axis perpendicular to the amorphous layer.

In this study, the authors researched the preparations of superhydrophilic/superhydrophobic surfaces on commercial cup stock polyethylene coated papers by using sparked aluminum nanoparticles deposited on substrates through a sparking process. In this stage, the surface was porous and showed superhydrophilic properties. The samples were then annealed in air at various temperatures and some transformed to superhydrophobicity. It is well known that a suitable roughness in combination with low surface energy has been required to obtain superhydrophobic surfaces. Therefore, it is believed that during annealing process, when polyethylene is diffused from the substrate through the nanoparticle films and the superhydrophobic characteristics were created. The scanning electron microscope images showed that the film surfaces had a fluffy structure for both the as‐deposited and the annealed samples. However, the atomic force microscopy phase images showed completely different surface properties. Moreover, the X‐ray photoelectron spectroscopy spectra showed different surface chemical compositions. The experimental results revealed that the working temperature to produce superhydrophobic surfaces depended on the sparked film thickness. Furthermore, in order to prove the assumption explained above, glass and poly (methyl methacrylate) were also used as substrates.
