“…In view of this, the use of AFM image processing to obtain stereometric parameters of surfaces has been widely studied in recent years (Stach et al, 2019;Sobola et al, 2020;Zaneta et al, 2017;Ţ alu et al, 2015). These measurements provide mechanisms for a better understanding of relevant aspects of a surface, like for example, roughness, peak distribution, hill regions, pit regions, and power spectrum density (PSD), among others.…”

The aim of this study was to report the first discussion of statistical parameters and possible applications related to the surface of kefir biofilms prepared with Maytenus rigida Mart. extract through micromorphology, using atomic force microscopy (AFM). Four different samples were produced. The reference contained demerara sugar with a concentration of 40 g/L and the others had added extract whose concentrations were 0.25, 0.50, and 0.75 g/L, respectively. AFM was used to image the surface in tapping mode, on square areas of 30 μm × 30 μm. Images were studied by the MountainsMap premium commercial software. The main parameter of the surface, roughness, grew with the increase of the extract concentration up to 0.50 g/L. In addition, asymmetry and kurtosis showed that the biofilm with the best peak distribution was the one with 0.25 g/L of plant extract. The other parameters followed the main results for the surface and were observed for the depth and volume parameters. The power spectrum density spectrum confirmed the reliability of the results for the sample with 0.25 g/L. Therefore, the sample with 0.25 g/L of plant extract produced the best balance in relation to the surface properties. These results showed that the biofilm morphology and microtexture were affected by the incorporation of the plant extract and can be useful to define possible applications.

“…Stereometric analysis was performed based on the AFM data because it provides true three-dimensional information about the surface texture. , Topography of the surface based on stereometric analysis was described using the SPIP-TM version 6.7.4 software, based on ISO 25178–2:2012 and ASME B46.1–2009 . The histograms of the height distribution of the AFM images (painted in blue) with their integration curves (painted in red) associated with the images are shown in Figure .…”

The purpose of this work is a stereometric analysis of Ni−Cu thin films to obtain the three-dimensional (3D) microtexture surface based on atomic force microscopy (AFM). Four Ni−Cu thin films on glass and silicon substrates were prepared by a capacitively coupled RF-PECVD system with a 13.56 MHz power supply. The AFM data of the samples were stereometrically analyzed, and the surface microtexture was determined according to the definition of relevant parameters in the standards ISO 25178−2:2012 and ASME B46.1−2009. All microtexture features can be implemented in numerical programs to simulate advanced microtexture models under specific microstructure and composition conditions. The results can be used to validate theoretical models for predicting or correlating the surface parameters of nanostructures. The Ni−Cu films with 40% Cu have a more irregular surface; hence, the maximum Sq value of the as-deposited Ni−Cu films is about 81.24 μm. The core roughness height Sk is calculated as a difference between two extreme levels (maximal and minimal) of the surface core, for which Ni−Cu films with 40% Cu have a maximum value of 183.4 μm. Since the surface kurtosis (Sku) of all sample films was lower than 7, there are very small peaks or valleys on the film surface and for Ni−Cu films with 5% Cu with a value of 3.568. With increasing Cu content, the height distribution histograms of films show more uniform distributions.

“…In the case of the ALD method, a chemical reaction occurs on the surface and only during heat treatment crystallites are formed on the surface. It was noted that thin Ta2O5 films were formed by the fractal mechanism [33]. This work also studied the correlation between the thickness of Ta2O5 thin films and their 3D micromorphology.…”

In this study a comparison of the topography of BiFeO3 (BFO) thin films deposited on tantalum pentoxide substrates of different thicknesses is provided. The Ta2O5 substrates had a roughness increasing with the film thickness. The relationship between substrates of different topography but the same composition with the quality of the growing bismuth ferrite film is estimated. For the first time the topography estimation of BFO on Ta2O5 is presented. The difference in temperature expansion coefficients leads to intensive evaporation of bismuth ferrite from the surface during annealing. XPS analysis is provided for asdeposited and annealed BFO layers.
