The operation of substrates within these electronics necessitates adherence to three primary criteria for the wiring of electronic substrates to facilitate the integration of stretchable circuits in society. First, the wiring’s top surface must remain exposed to allow for the straightforward attachment of electronic components following the wiring fabrication. Second, the design of the wiring pattern should not be subject to significant constraints. Third, the substrate’s top surface needs to be clean and devoid of excess conductive material to mitigate the risk of unintended short-circuits. Previous studies have not introduced a liquid metal patterning method that meets all of these criteria. Physical vapor deposition (PVD) is commonly employed for depositing hard metals on nonstretchable substrates such as silicon and glass. However, when subjected to direct PVD, liquid metal forms independent nanoparticles, losing conductivity due to its exceptionally high surface tension and the presence of surface oxide films. Consequently, the direct deposition of liquid metals without subsequent physical stimulation, such as the application of pressure, has been deemed challenging. In our study, we enhanced the substrate surface’s wettability by treating it with copper chloride, thereby facilitating the direct deposition of liquid metals onto the substrate surface. The oxide film on the liquid metal’s surface is disrupted upon contact with the copper chloride-treated substrate, enabling the nanoparticles to coalesce and establish electrical connectivity, thereby preserving conductivity even when stretched. The resultant stretchable wiring exhibited a fine line width of approximately 50 μm and a thin film thickness of approximately 1 μm, ensuring a robust bond with the substrate surface. Consequently, this wiring technique supports diverse patterning designs when combined with processing methods such as photolithography.</p>","PeriodicalId":3,"journal":{"name":"ACS Applied Electronic Materials","volume":"7 9","pages":"3656–3666 3656–3666"},"PeriodicalIF":4.3,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsaelm.4c02096","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143933707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SHI-generated sulfur vacancies show an excellent opportunity for varying the optoelectronic properties of the MoS₂ films. After 70 MeV Si⁴⁺ irradiation at a different fluence, the findings indicate a red shift in the out-of-plane vibration modes (A_1g) of the defective MoS₂ sheets’ Raman spectra. This red-shifting in the A_1g phonon mode indicates the systematic tensile strain generation and n-type behavior of irradiated MoS₂ sheets, which also influences the work function decrease of the MoS₂ film. More precisely, a 0.23 eV decrease in the work function of the 5 × 10¹³ fluence-irradiated MoS₂ films confirms the n-type behavior of defective MoS₂. Also, the defect density that provides both radiative and nonradiative active sites for electron–hole recombination may be modulated to influence the photoluminescence (PL) intensity of MoS₂; when the defect density increases, the overall PL intensity of the samples exhibits a monotonic reduction. Due to the strain-generated n-type behavior of irradiated samples, the defect-bound negative trions’ density improves with ion fluence. Also, the TRPL results show that the surface trapping and interband electron–hole recombination times continuously decrease with fluence.

Triboelectric nanogenerators (TENGs) have garnered significant attention as promising technologies due to their straightforward design, low cost, and suitability to collect low-frequency mechanical energy. Herein, a simple approach is proposed that combines electrospinning and a hydrothermal method to grow ZnO nanorods (NRs) on PVDF-HFP nanofibers (NFs). Growing ZnO NRs on PVDF-HFP NFs has formed Setaria viridis structures that enhance surface roughness. Additionally, surface modification through fluorination reduces the surface energy, thereby increasing the hydrophobicity. The resulting 1.0 wt % ZnO/PVDF-HFP TENG achieved remarkable performance, with an output voltage of 1200 V and a current density of 1.34 μA/cm², which is 4.68 times higher than pristine PVDF-HFP TENG. This significant improvement is attributed to the enhancement of the β phase of PVDF-HFP and the increased dielectric constant resulting from the growth of ZnO NRs on the PVDF-HFP NFs. In addition, the modified TENG demonstrated excellent capability for energy conversion from water droplets, yielding a maximum output voltage of 28 V and a current of 33 μA under optimized conditions (20 cm distance, 0.13 mL/s flow rate, and 45° water flow angle).
