It is one of the humans’ desired goals that we want to
precisely control the heat transport as the level as that we can
control the electrical current. However, a high-performance thermal
rectifier or thermal diode is still missing. Currently, researchers
at the Japan Advanced Institute of Science and Technology (JAIST)
have demonstrated a promising asymmetric graphene nanomesh device
that shows a high thermal rectification ratio at low temperatures.
The experiment provides a practical guideline for developing a
high-efficiency thermal rectifier based on graphene nanomesh
structure. The findings are published in Nano
Futures.
