Size-tunable Ge Nano-particle Arrays Patterned on Si Substrates with Nanosphere Lithography and Thermal Annealing
Bibliographic record
Abstract
Experimental studies on patterning hexagonal Ge nanostructures have been conducted on Si substrates through deposition of Ge with latex nano-spheres as a mask. The size distribution of the patterned Ge dots is narrow with the full width at half maximum being less than 10% of the dot size. By thermal annealing, a shape transition of the Ge nanostructures from original triangular discs to spherical or three-dimensional faceting dots was observed at a temperature of 650°C on the Si substrate bearing an oxide overlayer. With this process, a size modulation of the annealed Ge nano-particles can be achieved by varying the thickness of the initial Ge deposition. With this nanosphere lithography technique hexagonally patterned arrays of Ge dots of ∼ 30 nm in diameter were fabricated on Si substrates.

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.
