Effect of Substrate Temperature on the Epitaxial Growth of Oriented <i>n</i>-Alkane Thin Films on Graphite
Bibliographic record
Abstract
A complex orientational morphology is observed when n-alkane thin films are vapor deposited on highly oriented pyrolytic graphite surfaces. Substrate temperature can be used to tune the orientation and morphology of n-alkane thin films. The molecular orientation changes from lateral to normal to the surface when the substrate temperature is raised sufficiently. Under specific substrate temperature conditions, the n-alkane molecules are aligned in the plane of the sample surface, in directions reflecting the 6-fold symmetry of the graphite substrate. A series of different morphologies, from uniform thin films to oriented bars, are observed as a function of chain length and substrate temperature. The systematic evolution of these oriented morphologies is mapped as a function of deposition conditions, and the kinetic and thermodynamic factors that govern the formation of different in-plane and normal domains are considered.

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.
