Terahertz birefringence and absorption of a chalcopyrite CdSiP2 crystal
Bibliographic record
Abstract
The terahertz (THz) birefringence and absorption of a chalcopyrite CdSiP2 (CSP) crystal are studied at frequencies between 0.5 and 2.9 THz. Time-domain spectroscopy measurements are used to record the phonon-polariton dispersion and reststrahlen band absorption (centered at 2.03 THz) of CSP's lowest-frequency E mode. The ordinary and extraordinary refractive indices of this material, along with the extinction coefficients, are determined over the investigated frequency range. The uniform CSP birefringence (∼0.08) and the low extinction coefficient values (≤0.008) at frequencies between 0.5 and 1.9 THz suggest the potential for waveplate applications.

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.
