We also have synthesized polycrystalline double-thick-walled (DTW) SiC nanotubes. Herein, we report the successful synthesis of novel amorphous DTW SiC nanotubes for the first time. The degree of crystallinity of the SiC nanotube was decreasing with growing irradiation damage, and the SiC crystals were completely amorphized when irradiated at 3.2 dpa. According to these TEM images, the double-walled structure in the amorphous SiC nanotube was maintained even after ion irradiation. When the irradiation damage increased up to 24.0 dpa, the amorphous DTW SiC nanotube altered to the amorphous SiC nanowire., The 9th International Symposium on Surface Science (ISSS9)}, title = {Ion Irradiation Induced Synthesis of Novel Amorphous Double-Thick-Walled Silicon Carbide Nanotubes}, year = {2021} }
