Microscopic derivation of the microstretch theory for carbon nanotubes
Summary
arXiv:2606.03452v1 Announce Type: new Abstract: Twisted carbon nanotubes support phonons involving not only torsion, naturally associated with microrotation, but also radial breathing, which requires a scalar stretch degree of freedom. We derive an effective microstretch theory for these modes starting from nonlinear elasticity on a cylindrical surface. By linearizing the equation of motion around a uniformly twisted equilibrium configuration, we obtain the dynamical matrix for the twisting, longitudinal, and radial-breathing modes.
Why It Matters
This Semiconductors development reshapes the global chip supply chain and the race for advanced-node leadership. For Asia, it is a signal worth tracking: it shapes who supplies, who scales, and who sets the standard over the next five years.
