摘要：

Si nanowires (SiNWs) synthesized by laser ablation method exhibit different morphological characteristics such as straight, curved, kink, braided, and coiled shapes. These morphologies and their corresponding micro-structural aspects were examined in some details by transmission electron microscopy (TEM). It is found that the formation of various morphologies of SiNWs is closely related to the insertion of twins or the spatial twisting along the growth direction during the growth process of SiNWs.
