The field emission properties of a new design: multi-pixel carbon nanotube field emitters for imaging application
Bibliographic record
Abstract
In this study, a patterned cathode, on an n-type doped silicon resistor with a doping concentration of 1014cm-3and a cross section area of 1μm2, is designed for multi-pixel X-ray source with one anode. In this regard, individual carbon nanotube (CNT) field emitter arrays (FEAs) is fabricated by plasma enhanced chemical vapor deposition (PECVD) method on the Si cathode. The cathode has a density of 100×100 CNT arrays, and it is tested for x-ray generation at high voltage, the current and radiation dose are measured during the experiment. At the end of this work, we investigate a 3×3 multi-pixel X-ray source and see if the power of each X-ray pixel can be easily controlled and have more potential to achieve high resolution. For this purpose, COMSOL Multiphysics is used to simulate the electric field.

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.
