Nanostructured CdS prepared on porous silicon substrate: Structure, electronic, and optical properties
Bibliographic record
Abstract
Nanostructured CdS was deposited electrochemically on porous silicon (PS) substrate/cathode. The PS-supported CdS deposits were found to be uniformly packed particles of ∼100 nm, each of which is an aggregate of smaller clusters of several nanometers as revealed by scanning electron microscope and confirmed by glancing incidence x-ray powder diffraction. No significant CdS deposition into the pore of porous silicon is found under the reported experimental conditions. X-ray absorption fine structures (XAFS), both extended x-ray absorption fine structure and x-ray absorption near edge structures, across the S and the Si K edge of the samples have been investigated. The structure and electronic properties of the CdS/PS composite are discussed on the basis of the XAFS results obtained using multichannel detection (total electron and x-ray fluorescence yields) from a series of CdS and PS samples. The optical luminescence behavior of CdS/PS was also investigated utilizing a technique often referred to as synchrotron x-ray excited optical luminescence (XEOL). By selecting excitation photon energies near the Si and the S K edge, the luminescence originated from both CdS and PS can be distinguished in the XEOL spectra.

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.
