摘要：

Scalar phonon transport in helix nanobelts is studied by employing differential geometry method and formal scattering theory. Phonon transmission coefficients and thermal conductance are calculated. The numerical results reveal that curvature and torsion induce quantum interference between phonon modes, which makes the quantized stairs of the total transmission coefficient exhibit oscillation behavior which in turn suppresses the thermal conductance considerably.
