ABSTRACT
The Ga-assisted formation of Ge nanorods and nanowires in solution has been demonstrated and a catalytic activity of the Ga seeds was observed. The synthesis of anisotropic single-crystalline Ge nanostructures was achieved at temperatures as low as 170 °C. Gallium not only serves as nucleation seed but is also incorporated in the Ge nanowires in higher concentrations than its thermodynamic solubility limit.
摘要
已证明在溶液中通过镓辅助形成锗纳米棒和纳米线，并观察到镓籽晶的催化活性。在低至170°C的温度下实现了各向异性单晶锗纳米结构的合成。镓不仅作为成核籽晶，而且以高于其热力学溶解度极限的浓度掺入锗纳米线中。
