Abstract

fetched live from OpenAlex

In THz QWIPs, quantum well impact ionization rules electronic transport between two dierent regimes separated by huge shifts in the current and negative dierential resistivity behavior. This paper is dedicated to give some insight into the microscopic transport physical mechanism. The investigation of bias versus current measurements reveals that the rst two wells of the structure become partially drained, and that second well enters the ionized regime before the rst one. Both many body eects and a careful model of the contact have to be considered to account for these features. The use of this mechanism can lead to the design of very high gain fast THz detectors.

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.
