  • Bucky-shuttle as a memory element

    This simulation shows the functionality of a bucky-shuttle as a nanotube-based memory element. The outer capsule is a short segment of a (10,10) carbon nanotube, with a diameter of 1.4 nanometers, terminated at both ends by perfect fullerene caps. The capsule is large enough to hold a C60 buckyball molecule inside. The buckyball carries a net positive charge if it contains an alkali atom in the hollow cage. The C60 molecule can be shifted from one end to the other by applying an electric field between the ends of the capsule. The two energy minima of this system, with the buckyball bonded to either end of the capsule, can be associated with bit 0 and bit 1. This structure has been patented as a non-volatile memory element and awarded U.S. Patent Number 6,473,351.
