Elastic Stiffening Induces One-Dimensional Phonons In Thin Ta2Se3 Nanowires
What Has Been Achieved:
Demonstrates 1D phonon-mediated thermal transport in Ta2Se3 nanowires, which is enabled by a phonon stiffening effect.
Importance of the Achievement:
This work demonstrate 1D phonons through thermal conductivity measurements on Ta2Se3 nanowires. This result would motivate other researches to explore signatures of 1D phonon transport in other quasi-1D systems.
