Paper Title:
Structural Properties of Potassium Encapsulated in Carbon Nanotubes
  Abstract

We have investigated structural phases of potassium in carbon nanotubes using a structural optimization process applied to an atomistic simulation method. As the radius of the carbon nanotubes is increased, various structural phases ranging from an atomic strand to multi-shell packs composed of coaxial cylindrical shells and helical, layered, and crystalline structures are found to emerge. Numbers of helical atom rows composed of coaxial tubes and orthogonal vectors of a circular rolling of a triangular network can explain multi-shell phases of potassium in carbon nanotubes.
