Abstract
Methods and apparatus are provided for igniting, modulating, and sustaining a plasma for synthesizing carbon structures. In one embodiment, a method is provided for synthesizing a carbon structure including forming a plasma by subjecting a gas to electromagnetic radiation in the presence of a plasma catalyst and adding at least one carbonaceous material to the plasma to grow the carbon structures on a substrate. Various types of plasma catalysts are also provided.
