Single-crystalline CrSi(2) nanostructures with a unique hexagonal nanoweb morphology have been successfully synthesized for the first time. These nanowebs span 150-200 nm and are composed of <112̅0> nanowire segments with a thickness of 10-30 nm. It is proposed that surface charges on the {101̅0} sidewalls and the minimization of electrostatic energy induce the nanoweb formation. Calculations of the electrostatic energies were used to predict the transitions between different modes of bending, which agreed well with the experimental observations.
首次成功合成了具有独特六方纳米网形态的单晶 CrSi(2) 纳米结构。这些纳米网的跨度为 150-200nm，由厚度为 10-30nm 的 <112̅0> 纳米线段组成。提出了{101̅0} 侧壁上的表面电荷和静电能的最小化诱导了纳米网的形成。静电能的计算用于预测不同弯曲模式之间的转变，这与实验观察结果吻合良好。
