Investigations of sodium in bridgman-grown CuInSe<inf>2</inf>
Bibliographic record
Abstract
Measurements of thermoelectric power (¿) and electrical resistivity (¿) were made at room temperature on filamentary samples of CuInSe2(stoichiometric) and CuInSe2.2(excess Se), Bridgman-grown with added elemental sodium in the melt in the amounts of 0, 0.1, 0.2, 0.5, 1, 2 and 3 at. %. In the CuInSe2+ Na samples, conversion from p- to n-type occurred between 0.2 and 0.5 at. % Na, yielding electron concentrations of the order of 1016cm-3. By contrast, the CuInSe2.2+ Na samples remained p-type at all the sodium addition levels, yielding hole concentrations of the order of 1018cm-3. In the important range 0 to 0.5 at. % Na, where sample brittleness is less of a problem than for higher additions, no major changes occurred in hole mobility or resistivity but a small increase in ¿pand a small decrease in ¿ was apparent at 0.1 at. % Na.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
