Fullerene Shuttle Memory Device: Classical Molecular Dynamics Study

抄録

We investigated the internal dynamics of a bulky shuttle memory system, consisting of a C₃₆⁺ or C₆₀⁺ encapsulated in a C₆₄₀ nanocapsule. Energetics and operating response of a C₃₆⁺@C₆₄₀ and a C₆₀⁺@C₆₄₀ bucky shuttle memory device, such as transitions between the two states of the C₆₄₀ end caps, were examined by using classical molecular dynamics simulations of the C₃₆⁺ or C₆₀⁺ shuttle in the C₆₄₀ nanocapsule under the external force fields. For the stable operations of the shuttle memory device, the periods and the magnitudes of the operating force fields were investigated.
