However, the lack of research on size-dependent shear responses limits the structural design of Cu/Ta nanofilms. In this paper, molecular dynamics simulations are conducted to explore shear behaviors and failure mechanisms of Cu/Ta nanofilms with different modulation periods (λ). The findings indicate that the incoherent Cu/Ta interface forms a periodic misfit dislocation network after relaxation. The shear stress–strain curves for the samples display two distinct yield points. The shear modulus remains insensitive to variations in λ. The yield strength and yield strain of the sample at λ = 15 nm are significantly higher than those in the other cases. Defects tend to nucleate at the heterointerface where stress is concentrated. The specimens undergo four deformation stages at different λ: elastic deformation, yield of Cu, yield of Ta, and plastic flow. The shear failure is primarily associated with the Ta layer. The dislocation density in Cu decreases as λ increases, while no clear trend is observed in Ta. The shear bands first propagate from the interface into Cu and then extend into Ta. Moreover, the degree of strain localization in constituent layers becomes more pronounced with increasing λ.

Boron-containing dopants are a versatile group of materials that make it possible to conveniently tune PEDOT film structure and properties. Here, we investigated how several boron-containing dopants affect the structure and properties of electrodeposited PEDOT. The dopants examined were sodium tetrafluoroborate (NaBF<sub>4</sub>), sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (NaTFPB), and sodium tetraborate (Na<sub>2</sub>B<sub>4</sub>O<sub>7</sub>, Borax). We compared these results to a commonly used non-boron-containing dopant for PEDOT, lithium perchlorate (LiClO<sub>4</sub>). After electrodeposition, overall rough PEDOT film surfaces with varied morphological features, depending upon the utilized dopants were generated based on SEM. The low-frequency impedances of all PEDOT-coated electrodes were at least one order of magnitude lower than those of bare electrodes. The lowest impedances were observed for PEDOT/ClO<sub>4</sub> and PEDOT/BF<sub>4</sub>, correlated with their doping levels by reaching the maximum threshold of 33%. These two also had similar and higher areal-specific capacitances with the values of 9.4 and 10.3 mF/cm<sup>2</sup> than those of PEDOT/TFPB (3.3 mF/cm<sup>2</sup>) and PEDOT/B<sub>4</sub>O<sub>7</sub> (0.2 mF/cm<sup>2</sup>) on smooth gold surfaces. Although their areal-specific capacitances were similar, the volumetric-specific capacitance of PEDOT/BF<sub>4</sub> was 284 F/cm<sup>3</sup> and almost doubled that of PEDOT/ClO<sub>4</sub>. For screen-printed electrodes, the areal-specific capacitance of PEDOT/TFPB was almost similar to the other two types, with the values of approximately 6.0 mF/cm<sup>2</sup>.
