Dislocation-driven growth of single-crystal metal foils with high-index facets.

ABSTRACT: Single-crystal metal foil with high-index facets is an emerging metastable platform for 2D epitaxy, catalysis and electronics. However, its controlled growth has been plagued by the lack of a selective mechanism for driving diverse high-index facets. Here, we report a versatile strategy for the deterministic growth of single-crystal metal foils with diverse high-index facets. By incorporating dislocation energy differences to lift the free energy of strong (100) texture, we selectively activated the abnormal growth of high-index facets with an enhanced driving force, thus enabling the deterministic growth of single-crystal Cu, Ni and Au foils with dozens of high-index facets. Such energized growth leads to a counterintuitive discovery that increasing the driving force reduces the retarding
