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

These results establish a strong correlation between twin density and axial heterostructure formation, identifying defect control as a key factor in realizing monolithically integrated nanowire single-photon sources.

C2weakest assumption

That the observed improvement in axial QD formation is caused primarily by Sb-mediated suppression of rotational twins rather than other uncontrolled growth parameters, an assumption stated in the abstract but not quantified with systematic controls or growth models.

C3one line summary

Dilute antimony incorporation during nanowire growth suppresses rotational twins and enables abrupt axial InGaAs quantum dots with single-photon emission.
