We report the demonstration of thermomechanical data storage in a poly(methylmethacrylate) film using a multiwalled carbon nanotube (MWCNT) tip. Indentation densities of >250 Gbits/in[sup 2] are achieved. The power efficiency of indent writing with MWCNT tips is found to be higher than that of conventional silicon tips owing to better heat transfer at the tip–polymer interface. © 2003 American Institute of Physics.

    The introduction of tube-tube force constants derived from graphene interplane ones allows us to propose a simple model which describes the bundle effect in single-walled nanotubes. A typical 10-20 cm[sup-1] upshift of the radial breathing mode is predicted which depends on the tube diameter and...
