Abstract

fetched live from OpenAlex

This article describes a dynamic mode electrostatic force-gradient microscopy technique capable of high-frequency voltage measurement. The technique employs a wide-bandwidth implementation of a mechanoelectric cross-modulation scheme, where a microfabricated probe is driven by an amplitude-modulated sampling pulse and the sample is mechanically vibrated at a frequency different to that of electrical modulation. The resulting probe oscillation at the cross-modulation frequency provides local high-frequency voltage information. Unlike the force detection method, which is susceptible to poor resolution due to large coupling to the probe tip sidewall and cantilever, the force-gradient method provides an enhancement of spatial resolution. A significant reduction of interference from adjacent signal traces is demonstrated when performing integrated circuit testing. Quantitative high-frequency voltage measurement with high accuracy is achieved by using a null-force-gradient approach, but at the expense of reduced sensitivity.

Not 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.
