What is it about?
Unambiguous dependency of cross-plane thermal conductivity on thickness density of single crystalline Bi2Se3/In2Se3 superlattices is investigated, where a minimum in thermal conductivity indicates a crossover from particle-like to wave-like phonon transport.

Why is it important?
It is important to understand the thermal conductivity limit of superlattices for developing novel thermoelectric materials. Therefore, our creative study on the thermal conduction in bismuth chalcogenide superlattices paves the way for more profound research on this system.
