  • Low thermal conductivities in nanomeshes have been attributed to both wave-like and particle-like behaviour of phonons. Here, the authors use periodicity-controlled silicon nanomeshes to show that the particle backscattering effect dominates for periodicities above 100 nm and temperatures above 14 K.

  • Thermal analogues to electrical transistors offer the potential for heat flow switching and amplification. Here, the authors demonstrate a macroscopic magnetic thermal transistor with applications in thermal control and thermal logic circuits.

  • Preserving the large power factor of carbon nanotubes is challenging, due to poor sample morphology and a lack of proper Fermi energy tuning. Here, the authors achieve a value of power factor of 14 ± 5 mW m−1 K−2 originating from the preserved conductivity and the ability to tune Fermi energy.
