Diameter dependence of polarization resolved reflectance from vertical silicon nanowire arrays: Evidence of tunable absorption
Bibliographic record
Abstract
Vertical silicon nanowire arrays of different diameters ranging from 90 nm to 190 nm with a pitch of 400 nm are fabricated. Nanowires are arranged in a square lattice and have a length of 1 μm. Polarization resolved reflectances from these nanowire arrays are measured and significant differences are observed for the reflectance characteristics of the s- and p-polarized beams. A narrow wavelength band of increased absorption is reported by analyzing the reflectance using the finite difference time domain method. The center wavelength of this band shifts toward higher wavelengths as the diameter of the nanowires increases achieving tunable absorption spectra within the nanowires. The wavelength band shifts at a rate of approximately 3.3 nm with every 1 nm increment in diameter. The increased absorption is achieved due to modal excitation and near-field coupling between the nanowires.

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.
