Exploring Quantum Emission in Bilayer WSe<sub>2</sub>: Strain Effects from Nanopillars
Bibliographic record
Abstract
2D semiconductors subject to localized strain represent an emerging, scalable platform for the generation of bright single‐photon emitters. In this study, the observation of quantum emission from bilayer (BL) WSe2 under varying 3D strain induced by dielectric nanopillars is reported. Spectrally narrow and bright photoluminescence along with antibunched photon statistics is observed, comparable to those of monolayer WSe2, consistent with strain‐mediated quantum emission via defect states. The results indicate that the brightest emitters are created with pillar diameters ranging from 175 to 195 nm. A robust second‐order correlation function of g(2)(0) = 0.139 confirms strong antibunching, indicative of high‐quality single‐photon emission. These findings highlight the potential of using nanopillar arrays to manipulate the electronic states and quantum emission in transition metal dichalcogenide BLs, paving the way for future applications in quantum technologies.

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.
