Dynamics of 'Buckyshuttle'
as a 1-bit memory device
This is an abstract
for a poster to be presented at the
Foresight Conference on Molecular Nanotechnology.
There will be a link from here to the full article when it is
available on the web.
The concept of a buckyshuttle [a buckyball C60
confined but mobile in a short (10,10) nanotube segment] emerged
recently as a possible two-state element, with the C60
located at one or the opposite end of the tube. A triangular
array of such elements, if ever made, would have a maximum
capacity of almost 1018 bit/m2. The van der
Waals forces are responsible for the potential wells at the ends,
and for the friction on the way between them. We will analyze the
feasibility of this idea, the energetics, kinematics (when
switched between 0 and 1), and thermodynamic efficiency .
