Modulation period of Ag deposition on co-sputtered TiN-Ag leading to different microstructures: Implication on mechanical properties and living cells growth

Impurity Phases and Optoelectronic Properties of CuSbSe2 Thin Films Prepared by Cosputtering Process for Absorber Layer in Solar Cells

“…CuSbSe 2 thin films were deposited on 1 × 1 cm 2 Corning glass substrates using an RF magnetron cosputtering system (IDT Engineering Co., Gyeonggi, Korea) [24][25][26][27], as shown in Figure S1, with CuSe 2 (TASCO, Seoul, Korea, 99.99% purity, 2-inch diameter) target under a fixed power of 40 W and variable power for Sb (TASCO, 99.99% purity, 2-inch diameter) target from 13 to 21 W in increments of 2 W, while other parameters were kept constant using the following conditions: presputtering process for 5 min prior to each run, an Ar gas flux of 20 sccm, base pressure of 1.0 × 10 −6 Torr, substrate-to-target distance of 5.0 cm, and vacuum pressure of 7.5 × 10 −3 Torr during sputtering at room temperature. During the target cleaning procedure, the substrates were shielded with a shutter.…”

Study on the osteogenesis of rat mesenchymal stem cells and the long‐term antibacterial activity of Staphylococcus epidermidis on the surface of silver‐rich TiN/Ag modified titanium alloy

“…Also, the biological toxicity of silver ions is dose dependent, the design strategy to control their cellular and tissue toxicity may be to enable the silver-containing coating on the implant surface to provide controllable release of silver ions (Xie et al, 2019). In our previous study, we showed that nanoscale TiN/Ag multilayers with a smaller modulation period had excellent mechanical properties and cellular compatibility (Sun et al, 2016a). In this study, we constructed silver-rich nano-multilayers that contained silver and titanium nitride on the surface of titanium alloys, and realized con- the implant, and bacterial infections can lead to insufficient boneimplant bonding (Kamath et al, 2015).…”

“…Biomedical titanium alloy (Ti‐6Al‐4 V) plates with a diameter of 10 mm were carefully polished and ultrasonically cleaned several times in ethanol and deionized water. A detailed description of the multilayer deposition and ion implantation has been presented in our previous study (Sun et al, 2016b; Sun et al, 2017). TiN/Ag multilayers were prepared using a multiarc ion‐plating system (SA‐6 T, China) and different doses of Ag ions were implanted on the surface of the TiN/Ag multilayers using an ion implantation system (MEVVA80III‐100, China).…”

“…Due to its favorable hardness, corrosion resistance, and cytocompatibility, titanium nitride (TiN), has been applied to high speed cutting tools, oxidation‐resistant coatings, biomedical, and other industrial fields (Liu & He, 2005; Sabitzer et al, 2015). In our previous study, TiN/Ag multilayers were designed because the compactness of a multilayer was superior to that of a single‐layer structure, and the addition of a TiN/Ag composite multilayer on Ti‐6Al‐4 V was beneficial for improving mechanical properties (Sun et al, 2016a; Yu et al, 2017).…”
