Insights into the Nature of Quantum Emitters in Electron-Irradiated hexagonal Boron Nitride

Alexander H\"ogele, Anand Kumar, Anna Rupp, Bayarjargal N. Tugchin, Josefine Krause, Julien Ch\'ened\'e, Marijn Rikers, Mingi Kang, Mohammad N. Mishuk, Mouli Hazra, Thomas Pertsch, Tobias Vogl

Electron irradiation of hBN produces intrinsic quantum emitters stable in layers thinner than 10 nm, distinct from organic contaminants.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The combined results not only rule out organic contamination as the source of emission but also provide insight into the spectral variability, thermal stability, and vertical localization of the emitters generated in electron-irradiated hBN that was created without any pre- or post-processing.

C2weakest assumption

That the differential response to thermal annealing and oxygen plasma etching reliably distinguishes intrinsic defects from organic contaminants without the treatments themselves creating or destroying emitters in ways that mimic the expected contaminant behavior.

C3one line summary

Quantum emitters in electron-irradiated hBN are intrinsic material defects rather than organic contaminants, with demonstrated stability in sub-10 nm layers.
