Abstract

Going out on a limb: A combination of theoretical techniques, high-resolution microscopy, and energy-dispersive X-ray spectroscopy shows the role sulfur plays in branching phenomena during carbon nanotube (CNT) network growth. A model is proposed in which small amounts of sulfur are enough to trigger the growth of a budin a CNT, leading to kink formation and subsequent branch growth (see SEM image). (Figure Presented)
