Radiative heat transfer between two carbon nanotubes [PDF]

Scientific Reports, 2022
We analyze the radiative heat transfer between two parallel and infinitely long carbon nanotubes (CNTs). The radiative heat exchange is due to the difference between the Poynting vectors generated by the fluctuating currents when the CNTs are at ...
