For any wavelength of 365 nm, the electrical characteristic of Ag films was improved when the silver film was photo-sintered at higher light intensity and for longer irradiation duration. In distinct, substantial reduction with the resistivity was observed on the samples irradiated having a light intensity of 300 mW/cm2 . The minimum resistivity of 5.44 10-6 m (just about 3 instances in comparison with worth of bulk silver) was obtained in the Receptor Proteins Recombinant Proteins optimum photo-sintering circumstances of 300 mW/cm2 and 50 min. Related outcomes were obtained for a wavelength of 385 nm, even though the resistivity exhibited bigger values in all samples, suggesting the shorter wavelength of UV-LED are extra efficient for better electrical performance. The minimum resistivity of five.44 10-6 m (sheet resistance of 72.six m/sq), comparable value from Ag films photo-sintered with IPL [55], was obtained from the optimum photo-sintering situations (300 mW/cm2 and 50 min). Comparing to values of thermally sintered silver film (Figure 5), the films irradiated using the UV-LED modules appeared to have much better electrical conduction, irrespective of the wavelength. The significant changes in the electrical resistivity of Ag thin films Finafloxacin MedChemExpress depending on the sintering circumstances are attributed to various motives. Dziedzic et al. [56] suggested that when the curing temperature got greater, the mass and thickness on the conductive pillars inside the carbon/polyesterimide (PEI) composite films decreased, resulting in lower electrical resistance. However, there was no significant difference inside the thickness of Ag films based on the curing temperature or the sintering techniques (thermal and photo-sintering), while the as-pre.
