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

Our results resolve the mechanistic origin of tilted versus non-tilted 2D growth and establish a general interface-driven orientation selection rule linking substrate symmetry and dangling-bond coordination to layered heteroepitaxy.

C2weakest assumption

The assumption that observed differences in morphology arise primarily from substrate preparation methods rather than uncontrolled variables such as exact growth temperature, flux ratios, or residual contaminants, and that results on these two orientations generalize to a broad selection rule.

C3one line summary

Substrate surface preparation controls whether 2D GaSe grows tilted or flat on GaAs, establishing an interface-driven orientation selection rule based on substrate symmetry and dangling-bond coordination.
