THE GROWTH MODEL OF QUASI-ONE DIMENSIONAL CARBON MATERIAL BASED ON VLS THEORY

VLS theory can be efficiently used in the analysis of one dimension carbon material synthesis. Under the catalytic effect of nickel particles, spring-like carbon filaments were synthesized through microwave plasma chemical vapor deposition. Based on the formation mechanism of carbon filaments and VLS theory, a simply and efficient diffusion model was proposed to analyze the effect of catalyst on the morphology of quasi-one-dimension carbon materials. It shows that differ in the diffusion rate along the circumference of catalyst is the main reason for the curly growth of carbon materials.
