Abstract
Gas ionization sensors (GISs) based on n-type and p-type ZnO nanowires (NWs) have been fabricated and successfully tested in field ionization (FI) and field emission (FE) modes in sub-Torr atmospheres of various gases (Ar, He, N 2 , and O 2 ). Novel GISs demonstrated good stability and low breakdown voltages. Significantly decreased electrical breakdowns in gases were attained in the vicinity of positively charged p-type ZnO NWs' tips. The applied voltages were less than 40 V. These experimental outcomes can be ascribed to the fact that Ag-doped ZnO NWs have an increased number of empty states below the Fermi level and because of the observed high curvature on the NWs' apexes. The calculated enhancement factors were 45 and 1.49 10 4 in the GIS based on n-type ZnO NWs and in the GIS based on p-type ZnO NWs, respectively. The novel GIS based on p-type ZnO NWs described here is inexpensive, simple in operation, consumes little power, and can be used for environmental monitoring and gas detection in industrial and living environments or for space applications.

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
