Optical Properties of Colloidal Photonic Crystals Confined in Rectangular Microchannels
Bibliographic record
Abstract
Herein we report experimental and theoretical analysis of the optical properties of planarized self-assembled colloidal photonic crystals confined within rectangular microchannels. A detailed mapping of the optical features, performed by microspectroscopy, is presented, providing evidence that spherical colloids confined in microchannels crystallize as single-domain colloidal crystal several hundreds of microns long with a very low concentration of intrinsic defects. A study of defective colloidal crystals is also made to illustrate this point. The effect of the different parameters affecting the reflection properties of these structures, such as crystal size, orientation, and nature of the substrate, is also analyzed. We show that the well-defined geometry and dimensions of the channels serve to template colloidal crystals with precise size, shape, and orientation, which imply accurate control of their photonic crystal properties.

How this classification was reachedexpand
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.
