Abstract
We present in this paper measurements of near-field heat transfer across sub-micron gaps between suspended membranes and their substrate. A microfabrication process using amorphous silicon as a sacrificial layer is developed to create membranes (50 μm × 50 μm) with nanoscale separation distance (down to 250 nm). In this configuration, evanescent near-field radiation couples between the membrane and the substrate, which is expected to enhance the heat transfer. Experimental measurements using an embedded heater and thermistor on the membrane demonstrate the enhancement of heat transfer at the smaller gaps, reaching radiation levels beyond the ideal black body. This is the first demonstration of near field heat transfer over large areas in a fully microfabricated device including a gap effect study.

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
