Crystal growth velocities $v_g$ (m/s) computed as described in Methods for the GeTe slab confined by the TiTe₂-like capping layers (GeTe/TiTe₂-like SL) for the bulk models (see text) with a thick (28 layers, Bulk28) molten region in contact with a crystalline slab and from homogeneous crystal nucleation and growth (Bulk_homo). At 700 and 750 K no crystal nucleation occurs in the bulk over the time scale of several ns.
