We deliberate on the conditions favorable to the growth of metallic crystalline superlattices (MCS) with (111) f.c.c./(110) b.c.c. interfaces. We use, with some motivation, equilibrium criteria (i) to justify the occurrence of the Kurdjumov-Sachs (KS) and Nishiyama-Wassermann (NW) orientations, and to show with analyses which also allow for elastic relaxation, that only the NW orientation that occurs at n.n. distance ratios in the interval 0.8 ≲ bf.c.c / ab.c.c ≲ 1.0 can yield the regular orientational relationships required for high quality MCS; ahd(ii) to show that, for the acquisition of the required smoothness of the interfaces, which is mainly determined by the growth mode - monolayer-by-monolayer (FM = Frank-van der Merwe) or island nucleation and growth (VW ≊ Volmer-Weber) mode - it is desirable to use material combinations with small surface free energy mismatch. Only then can VW growth (which inevitably occurs in each superlattice period) at relatively high supersaturation be FM-like and with low density of defects.
