Morphological control of laser-synthesized silicon nanoparticles.
Size and crystallinity controlled silicon nanoparticles were prepared by a laser ablation, in situ annealing and mobility size-selection with a differential mobility analyzer (DMA). The shape and crystal structure of generated particles were observed by a transmission electron microscopy (TEM). Both densification of agglomerates and crystal growth of the particles were observed. The size of silicon primary particle was increased by the annealing, and the uniformity of the particle classified at 10 nm was improved as a result.
