Height Dependence of Young's Modulus for Carbon Nanopillars Grown by Focused-Ion-Beam-Induced Chemical Vapor Deposition
Bibliographic record
Abstract
We investigated the height dependence of the Young's modulus for carbon nanopillars grown by focused-ion-beam-induced chemical vapor deposition (FIB-CVD) using phenanthrene gas as a source material. Carbon nanopillars of different heights were grown by FIB-CVD at various growth times and a fixed ion-beam focal point. The growth heights ranged from 3.6 to 35.6 µm. The diameters at the bottoms of the pillars were nearly the same, 100 nm, and it increased as the growth progressed. Young's modulus of the carbon nanopillars was evaluated from resonant frequency for mechanical vibration using uniform and nonuniform models. Young's moduli differed for different growth heights for both of the models.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
