Phonon counting
WebApr 13, 2024 · The radial-breathing-like phonon modes (RBLMs) of the double-walled carbon nanotubes are studied in a simple analytical model, in which the interaction force constants (FCs) can be obtained analytically from the continuous model. Websation of phonon branches occurs for higher dimen-sional lattices. Acoustic branches have linear disper-sion ! ⇠ k for low momenta, while optical branches have non-vanishing frequency, typically higher than the acoustic branch. The data for the phonon spec-trum of NaCl is shown on the right6 and clearly ex-hibits these features.
