Resonance properties and microstructure of ultracompliant metallic nanoelectromechanical systems resonators synthesized from Al–32at.%Mo amorphous-nanocrystalline metallic composites
Bibliographic record
Abstract
This study details the resonance properties of 20nm thick nanoelectromechanical system scale cantilevers fabricated from a metallic Al–32at.%Mo nanocomposite. The advantage of the Al–32at.%Mo alloy is that its strength and near-atomic surface smoothness enable fabrication of single-anchored metallic cantilevers with extreme length-to-thickness ratios, as high as 400:1. This yields uniquely compliant structures with exquisite force sensitivity. For example, an 8μm long, 20nm thick Al–32at.%Mo device has a spring constant of K≅280μN∕m. We show through transmission electron microscope analysis and continuum modeling that the relevant damping mechanisms are related to the device microstructure.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
