Abstract
Bimetallic Cu–Ag conductive structures hold great promise in integrating flexible electronics, but fabrication of these structures requires complex multistep processes with poor controllability. Herein, we develop a one-step laser writing process for manufacturing the flexible Cu–Ag conductive structure from a metallic salt. The effect of laser parameters and precursor traits on the writing process, as well as the joining mechanism of Cu–Ag nanostructures, has been discussed systematically. The fabricated Cu–Ag structure not only exhibits remarkable conductivity with a resistivity of ∼8 μΩ cm but also has excellent oxidation and electrochemical migration resistances. Flexible electronic devices fabricated from these written structures, such as the flexible heater, were demonstrated as a proof of concept, thereby demonstrating excellent stability even in high-humidity-and-temperature working conditions.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
