Abstract

fetched live from OpenAlex

Strained layer superlattices based on Sb semiconductor material are proposed for long wavelength photodetector applications. Theoretical studies on the band structure of AlGaSb/GaSb, AlInSb/InSb, and GaInSb/InAs superlattices show that the wavelength coverage can be extended from 0.5 to 30 micrometer. Optical absorptions of the superlattices are calculated taking into account the intermixing effect at different diffusion lengths. Responsivity and detectivity of the GaInSb/InAs superlattice detector are also analyzed. Blue shift of responsivity is observed for increased intermixing and the detectivity D* at 77 K is increased by more than one fold in magnitude as R0A increases linearly with intermixing.

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.
