Abstract

An energy criterion is proposed for the level of agglomeration (coalescence) of nanowires fixed at the base on a rigid substrate and immersed in a continuous medium (air, liquid), which excludes capillary phenomena. This criterion, based on the competition between the elastic energy of a bent nanowire and its surface formation energy, can also be applied to the attachment of nanowires to a surface and (in a modified form) to the coalescence of details of micro- and nanomachines. Nanowires for surface-enhanced Raman scattering, obtained by template synthesis based on track membranes, with subsequent removal of polymer, are considered as a specific example.

用于表面增强拉曼散射的衬底上纳米线的团聚

摘要

针对固定在刚性基底上并浸入连续介质（空气、液体）中的纳米线的团聚（聚结）水平提出了能量标准，这排除了毛细管现象。该标准基于弯曲纳米线的弹性能与其表面形成能之间的竞争，也可以应用于纳米线与表面的连接以及（以修改的形式）用于微和纳米机器细节的结合. 用于表面增强拉曼散射的纳米线，通过基于轨道膜的模板合成获得，随后去除聚合物，被认为是一个具体的例子。
