A two-dimensional drift-diffusion model of THz emission from n-GaAs and InAs surfaces in a magnetic field (Invited Paper)
Bibliographic record
Abstract
We present a model of THz emission enhancement from femtosecond pulse excited n-GaAs and InAs surfaces with the application of a dc magnetic field. The far-field THz emission at different optical excitation densities, magnetic field strengths, and magnetic field orientations is determined. The model accurately describes the power dependence of THz emission from n-GaAs and InAs surfaces for magnetic field strengths up to ±10 T and ±6 T, respectively. THz emission saturation in both semiconductors for optical excitation densities from 40 nJ/cm<sup>2</sup> to 2.2 μJ/cm<sup>2</sup> are in accordance with previously reported experimental data. The model provides a useful tool for the description of ultra-fast processes in semiconductors.

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.
