Abstract

fetched live from OpenAlex

Photodetectors and photovoltaic devices composed of direct bandgap semiconductor materials absorb visible to infrared wavelengths within a few micrometers of material. Minority carrier diffusion lengths in such materials are critical in designing these optoelectronic devices for particular applications. Minority holes in InGaAs on InP are reported between 0-100°C for doping concentrations ranging between non-intentionally doped (NID) to 5E16 cm-3. At room temperature, values range between 81±8 μm for the NID sample to 34±1 μm for 5E16 cm-3. These values appear constant over the temperature range explored, implying that lifetime and mobility balance out.

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.
