Abstract

fetched live from OpenAlex

Activationless electron–hole generation and recombination in type II semimetallic single and double quantum wells is studied. An 8 × 8 k · p matrix Hamiltonian, and the transfer matrix method, is used to calculate the recombination rates for quantum wells made from InAs and GaSb. This model includes the non-parabolicity and anisotropy of the energy band structure. Because the conduction band of InAs lies beneath the valence band of GaSb, the generation and recombination processes do not require extra excitation particles such as phonons or photons. The effect of externally applied electric and magnetic fields is also included in the calculation of the recombination rates and both n-type and p-type single and double quantum wells are considered.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
