The periodic boundary conditions force the formation of a free-standing nanofiber exposed to a vacuum. After the deep quench, the nanofiber adopts a configuration dominated by extended chains aligned parallel to the fiber axis. The vicinity of the fiber axis is less dense, and less well ordered, than portions of the fiber located further from the fiber axis. Annealing finds that this low-density region inside the fiber is not as easily removed as is the grain boundary that usually develops inside a free-standing thin film upon rapid crystallization.
