Low-Temperature Deterministic Growth of Ge Nanowires Using Cu Solid Catalysts

Cu‐Catalytic Growth of Ge Nanowires: Low temperature, deterministic growth characteristics are available by the Cu‐catalytic growth. The low‐temperature growth is accessible at as low as 200 °C on polymer substrates, and the epitaxial growth is also possible on single‐crystalline substrates with the narrow diameter distribution of 7 nm, directly templated from those of Cu catalysts.
