Characteristics of CuInSe/sub 2/ Bridgman ingots grown with sodium [solar cell manufacture]
Bibliographic record
Abstract
Crystals of CuInSe/sub 2/ were grown by a horizontal Bridgman method for the first time with metallic sodium. The amount of sodium was varied with levels at 0.05, 0.25 and 2 at.% approximately. However, as the sodium content was increased, the crystalline quality decreased. Hot probe measurements showed that the ingots grown with higher sodium content (0.25 and 2 at.%) were n-type, while the ingot with about 0.05 at.% was p-type. Electron probe microanalysis and an Auger profile showed no detectable sodium (i.e.<0.1 at.%) in the ingots, even up to 2 at.% added to the melt. X-ray Laue back reflection, performed on the as-grown surface of the p-type CuInSe/sub 2/ ingot, confirmed the region to be single crystal. Powder X-ray diffraction patterns confirmed the chalcopyrite structure for all the ingots grown with sodium. Resistivity and carrier mobility in these ingots were obtained by Hall effect measurements. Metallic sodium was also introduced into already-grown CuInSe/sub 2/ monocrystals within a sealed glass ampoule and the characteristics of these samples were also analyzed.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
