Surface-phononic carbon nanotubes
Carbon nanotubes (CNTs) are known for their exceptional electronic properties, but defects often induce scattering and thus hinder performance. Taking inspiration from CNTs' electronic band structure, this study introduces phononic CNTs for controlling surface acoustic waves (SAWs). Phononic CNTs support two distinct, chiral SAW bands and exhibit strong resistance to scattering, enabling efficient SAW propagation. With their broad bandwidth, antireflection properties, and minimal loss, these tubes offer a promising solution for application in high-performance acoustics and phononics.
