Abstract
We have experimentally observed and modeled a second-order transport mechanism near breakdown in large-diameter (small-gap) semiconducting SWNTs. We determine impact ionization to be the primary cause of the up-kick in current. Subsequent simulations taking impact ionization into account provide a theoretical match to our experimentally observed current tail.
