Electrochemical Deposition of Chromium Core−Shell Nanostructures on H−Si(100): Evolution of Spherical Nanoparticles to Uniform Thin Film without and with Atop Hexagonal Microrods
Bibliographic record
Abstract
High Resolution Image Download MS PowerPoint Slide Electrodeposition in Cr(VI) and Cr(III) aqueous electrolytes is found to produce, respectively, granular and spherical core−shell nanoparticles on H-terminated Si(100). For the granular nanoparticles obtained by electrodeposition in CrO 3 and H 2 SO 4 electrolyte solution, both the morphology and number density remain discernibly similar while the particle size increases with increasing charge transfer. In the CrCl 3 electrolyte, evolution of the spherical nanoparticles to homogeneous Cr films without and with atop hexagonal microrods with increasing charge transfer is observed. The viability of producing a homogeneous Cr film on the Si substrate is therefore demonstrated. Both the granular Cr nanoparticles and the Cr film consist of predominantly Cr metallic core and Cr 2 O 3 outer shell covered by surface CrO 3, while the novel hexagonal microrods are made up of a metallic Cr core and a CrOOH shell.

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.
