通过最近推导的库仑相互作用表达式，研究了定向附着生长中生长的纳米棒和附着的纳米颗粒之间的库仑相互作用的动态演化。通过将长径比引入到各个评价中，详细分析了库仑相互作用与电荷密度、长径比、合成温度和纳米颗粒-纳米棒分离等参数之间的相关性。该分析从能量的角度极大地提高了我们对动态定向依恋增长的理解。
The dynamic evolution of the Coulombic interaction between a growing nanorod and an attaching nanoparticle in oriented-attachment growth is investigated via a recently-derived Coulombic interaction expression. With the incorporation of aspect ratio into each evaluation, the correlation between the Coulombic interaction and parameters including charge density, aspect ratio, synthetic temperature and nanoparticle-nanorod separation, is analyzed in detail. The analysis largely improves our understanding of the dynamic oriented-attachment growth from a fundamental energy perspective.
