Semiconductor nanochannels in metallic carbon nanotubes by thermomechanical chirality alteration

Abstract: "Carbon nanotubes have a helical structure wherein the chirality determines whether they are metallic or semiconducting. Using in situ transmission electron microscopy, we applied heating and mechanical strain to alter the local chirality and thereby control the electronic properties of individual single-wall carbon nanotubes. A transition trend toward a larger chiral angle region wa... » read more
