Electron-to-Hole Mobility Ratio in P-Type Bridgman-Grown CuInSe2 from Room Temperature Transport Measurements
Bibliographic record
Abstract
Room temperature measurements were made of electrical conductivity (sigma), Hall coefficient (RH) and Seebeck coefficient (alpha) on filamentary samples of p-type CuInSe2and CuIn1-xGaxSe2with xles0.3, cut from vertically grown Bridgman ingots. Analysis of the results was done on a two-carrier basis, due to the higher ratio of electron-to-hole mobility (b) in these materials compared to elemental semiconductors. This treatment yielded a preferred b-value of 5 and to lower calculated hole concentrations than (RHe)-1and higher hole mobilities than RHsigma, based on a one-carrier interpretation. This effect was particularly marked in p-type samples with a hole concentration below 1017cm-3, where even a few percent of minority electrons can play an important role

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.
