Simple models of nanoscale carbon structures

Click For Summary
SUMMARY

This discussion focuses on the stability and geometry of nanoscale carbon structures, specifically fullerenes and single-walled carbon nanotubes. Key inquiries include the relationship between the number of carbon atoms (C60, C70, Cx) and the energy of buckyballs, as well as the potential energy calculations for an armchair carbon nanotube with a 1.4 nm inner diameter in vacuum. The discussion also explores the feasibility of bending nanotubes into specific geometries, such as a torus, and the conditions required for stability. Jerzy Cioslowski's work on fullerenes is referenced as a foundational resource for further exploration.

PREREQUISITES
  • Understanding of nanoscale carbon structures, including fullerenes and carbon nanotubes

Hello - I am searching for some guidance, and I would greatly (greatly) appreciate any tips, pointers, etc.

I am interested in the stability and geometry of nanoscale carbon structures, such as fullerenes and single-walled carbon nanotubes. I am wondering where to begin to develop - for my own personal interest, not for any real research! - simple models of these structures.

The sorts of questions I am curious about are: C60, C70, Cx - how is x related to the energy of the buckyball, or the radius? How can I calculate the potential energy of a carbon nanotube, say an armchair with inner diameter 1.4 nm, in vacuum? Could I bend a nanotube into some specific geometry - IE, like a torus? What conditions would result in this structure being stable in vacuum? If it was unstable, what magnitude force would I have to symmetrically exert around it to keep it together?

Are there any books I should try to get a copy of to help start me off on this quest? Are there any pre-established models, or basic physical ideas, that would be useful in guiding me?

Thank you for any words you could provide me.
