TL;DR: In this paper, a Pt-decorated SnO 2 nanoparticles (NPs) were prepared using sol-gel and hydrothermal methods and screen printed on alumina substrates with Pt test electrode to fabricate the gas sensors.

TL;DR: In this article, the influence of nitrogen ion implantation on the properties of copper oxide thin films, prepared using DC magnetron sputtering, was investigated by means of X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy, and UV-visible spectrophotometer.

TL;DR: In this paper, the 3D surface morphology of aluminum nitride (AlN) epilayers on sapphire substrates prepared by magnetron sputtering was studied by combination of atomic force microscopy (AFM) and fractal analysis methods.

TL;DR: In this paper, the 3D surface morphology revealed the fractal geometry of Cu thin films at nanometer scale, which can be quantitatively estimated by the Fractal dimension Df that was determined by cube counting method, based on the linear interpolation type.

TL;DR: In this paper, the surface texture of amorphous hydrogenated carbon films with sputtered iron nanoparticles (FeNPs@a-C:H) was analyzed using a radio-frequency plasmaenhanced chemical vapor deposition method on the quartz substrates.
