Nanocantilever arrays were formed on the edges of the +/- (0001) planes of pre-synthesized ZnS nanoribbons via catalyst-assisted post-annealing treatment on Si substrate at 600 degrees C. Similar nanostructures could also be generated when ZnS nanoribbons were annealed by mixing with Si or SiO powder. The formation of nanocantilever arrays is associated with orientation-dependent chemical etching of the +/- (0001) polar surfaces of ZnS nanoribbons. The ability of increasing structural complexity beyond the one-step "thermal evaporation and condensation" synthesis provides a new dimension to the rational design of building blocks for nanodevices.
通过在600摄氏度的硅衬底上进行催化剂辅助的后退火处理，在预合成的ZnS纳米带的+/- (0001)平面边缘形成了纳米悬臂阵列。当ZnS纳米带与Si或SiO粉末混合退火时，也可以产生类似的纳米结构。纳米悬臂阵列的形成与ZnS纳米带的+/- (0001)极性表面的取向依赖性化学蚀刻有关。超越一步“热蒸发和冷凝”合成增加结构复杂性的能力为纳米器件构建块的合理设计提供了一个新的维度。
