Curved regions in hBN flakes enhance the spectral purity of quantum emitters at room temperature through strain-driven phonon redistribution.

Claims

C1strongest claim

Quantum emitters localized within these curved regions exhibit markedly enhanced room temperature spectral purity, with Debye Waller factors of 0.91 and narrower line widths than emitters in flat regions. Supported by first-principles calculations, we attribute this behavior to strain driven phonon redistribution, which depletes phonons in tensile regions and accumulates them in compressive regions.

C2weakest assumption

That the emitters are physically located inside the strained curved volumes rather than nearby flat regions, and that the observed phonon-mode splitting and coherence gain are caused by the strain-induced redistribution rather than by changes in defect chemistry or selection of different emitter types during measurement.

C3one line summary

Strain from curvature in hBN suppresses phonon coupling for defect emitters, yielding room-temperature Debye-Waller factors of 0.91 and single-photon emission with reduced linewidths.
