Light induced 2D chiral structure on the surface of azo‐polymer films
Bibliographic record
Abstract
Abstract In this experimental work, we present a simple method for fabrication of 2D chiral structure on the surface of an azo‐polymer film. It has been shown that illuminating of an azo‐polymer film with a single uniform laser beam can create the surface relief pattern on the surface of the film. For different state of polarization different structures are obtained. Under ∼33° incidence angle and for 45° polarization direction, the formed structure is asymmetric, and it does not have a symmetry axis in the 2D plane. The AFM images of these patterns are not superimposable with their mirror images if we rotate the images in their planes. On the other hand, the mirror images of Fourier Transform of AFM images also are not coinciding with Fourier Transform of AFM images. Consequently, this structure is a 2D chiral structure. These patterns are shown the capability to rotate the polarization state of diffracted light in the transmission regime. The changes in the polarization state of light associate with the chirality of sample. This is a one‐step very simple and reversible method to fabricate 2D chiral systems (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

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.
