dc.description.abstract A solution based synthesis of well-ordered Cu-rich silicide nano-architectures, consisting of a pair of layered cups and stems (ρ-Cu15Si4 ) is demonstrated. The as-grown ρ-Cu15Si4 typically exhibits distinct interconnected 1D stems, consisting of a stack of nanorods (∼300 nm in length), terminated with concave hexagonal 3D cups that evolve through a self-regulated layer-bylayer growth mechanism. Discrete-time ex situ experimental observations reveal that the ρ-Cu15Si4 evolution is driven by interatomic diffusion, initially triggering the formation of binary-phase silicide islands (spheres) followed by the formation of hexagonal discs, stem growth, and lateral elongation in exactly opposite directions. It is further shown that electrochemically pre-grown Cu-crystals can facilitate direct growth of the ρ-Cu15Si4 in high yield with enhanced substrate coverage. en_US
