“…It is known that important intensity such as our case could be interesting for optoelectronics devises (nanocrystals, grain size of the crystal and/or doping influence the emission of semiconductors which is beneficial for light in specific range or domains). We have found in recent work, that the variation in value of band gap is as a result of the structural difference (nanowires for doped film and dense for non-doped one) and the dopant element (PbS or Pb) for nanowires film [36].…”

“…Photoluminance (PL) characterization emission spectra of PbS:ZnO film are shown in Figure 7-b. The small peak at 380 nm (3.26 eV) due to optical band gap of ZnO materials in two substrates (Si in black color and glass in red color) [36], The another peak shows at about 525 nm matched to the defects in the film (electrons transition to vacancies of sulfur).

We obtained ZnO Nanowires films deposited on two types of substrate (Si (100) and glass) with 12 wt % PbS as dopant by simple thermal evaporation technique. High Resolution Transmission Electron Microscopy (HRTEM) and Energy-dispersive X-ray spectroscopy(EDX) images have confirmed the formation of ZnO Nanowires (NWs). EDX technique was used to investigate the elements content (standard analysis and mapping modes). Morphology and thickness of the films were investigated from surface and cross section of the films via Scanning Electron Microscopy (SEM) images. The Raman, photoluminescence (PL) and X-ray Diffraction (XRD) have confirmed the hexagonal phase structure of the ZnO Nanowires, which appeared to be very fine and their diameters were less than 40 nm and their lengths were of several micrometers using SEM and HRTEM. The effect of PbS as dopant on the growth of ZnO Nanowires as well as on the morphology for two substrates was investigated and compared. These Nanowires films could be applied in several fields. Mapping -EDX has confirmed the stoichiometry of prepared films. Finally, the structure (phase) was verified by different characterization techniques. The optoelectronic application of Nanostructures film will be study later.

“…Although the development of HEA systems has been going on for more than a decade, there are few reports on the deposition of stable protective films on HEA surfaces by conventional reactive sputtering techniques. Many studies have shown that sputter deposition of CrN film on conventional stainless steel is beneficial for its wear and corrosion resistance [ 25 , 26 ]. The CrN film deposited on the surface of 316 stainless steel has a positive effect on the friction behavior in NaCl solution and high temperature environments until heated to 550 °C [ 27 ].…”

In this study, Co, Cr, and Ni were selected as the equal-atomic medium entropy alloy (MEA) systems, and Si was added to form CoCrNiSi0.3 MEA. In order to further improve its wear and corrosion properties, CrN film was sputtered on the surface. In addition, to enhance the adhesion between the soft CoCrNiSi0.3 substrate and the super-hard CrN film, a Cr buffer layer was pre-sputtered on the CoCrNiSi0.3 substrate. The experimental results show that the CrN film exhibits a columnar grain structure, and the film growth rate is about 2.022 μm/h. With the increase of sputtering time, the increase in CrN film thickness, and the refinement of columnar grains, the wear and corrosion resistance improves. Among all CoCrNiSi0.3 MEAs without and with CrN films prepared in this study, the CoCrNiSi0.3 MEA with 3 h-sputtered CrN film has the lowest wear rate of 2.249 × 10−5 mm3·m−1·N−1, and the best corrosion resistance of Icorr 19.37 μA·cm–2 and Rp 705.85 Ω·cm2.

“…CrN was proven as a great option for protective coatings applications due to its hardness, low coefficient of friction and great corrosion resistance [9][10][11][12][13][14]. Moreover, CrN exhibits good heat resistance [15,16] and great thermal stability [9,17].…”

Chromium Nitride thin films are known for their good mechanical properties. We present the characteristics of ultrathin Chromium Nitride films under 400 nm thickness deposited on silicon substrates by direct current and high-power impulse magnetron sputtering techniques. The methods of investigation of the CrN films were scanning electron microscopy, atomic force microscopy, and nanoindentation. Qualitative and quantitative analysis were performed using the AFM and SEM images by fractal dimension, surface roughness and gray-level co-occurrence matrix methods. Our results show that using the mag-netron techniques, ultrathin CrN films with excellent mechanical properties can be obtained.
