Abstract

Here, we show a novel solid-solid-vapor (SSV) growth mechanism whereby epitaxial growth of heterogeneous semiconductor nanowires takes place by evaporation-induced cation exchange. During heating of PbSe-CdSe nanodumbbells inside a transmission electron microscope (TEM), we observed that PbSe nanocrystals grew epitaxially at the expense of CdSe nanodomains driven by evaporation of Cd. Analysis of atomic-resolution TEM observations and detailed atomistic simulations reveals that the growth process is mediated by vacancies.

摘要

在此，我们展示了一种新型的固-固-气（SSV）生长机制，通过蒸发诱导的阳离子交换实现异质半导体纳米线的外延生长。在透射电子显微镜（TEM）内加热PbSe-CdSe纳米哑铃时，我们观察到PbSe纳米晶体以CdSe纳米域为代价外延生长，这是由Cd的蒸发驱动的。对原子分辨率TEM观察结果和详细的原子模拟分析表明，生长过程由空位介导。
