Synthesis and characterization of thin films of chalcogenide semiconductors doped with transition metals with photovoltaic applications
Bibliographic record
Abstract
The influence of doping on properties of CdS thin films grown by chemical bath deposition technique is studied.Cu, Co, Ni and La are use as doping elements varying de proportion from 1 to 5%.The synthesis parameters employed were reaction time 120 min; speed stirring 240 rpm at a bath temperature of 75°C and pH are controlled at 10.The doped films with different elements are characterized employed optical and structural techniques such as XRD, UV-Vis and the surface morphology are evaluated through SEM.The films are polycrystalline with a mixture of hexagonal and cubic phases, the slope of absorption edge changes with the elements showing different trends mainly for Cu 2+ y el La 3+ .The valor of Eg decreases with increase of the metal quantity in case of Cu, Ni and La on the contrary of Cobalt.Films are formed by semispherical cluster, is slightly affected, the size increase in case of Ni and Co, and it is decreases for La and Cu.

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.
