Abstract
A thermal diode includes: a dielectric enclosure having a top surface, a bottom surface, a first side, and a second side; a first Weyl semimetal nanoparticle disposed on the first side; a second Weyl semimetal nanoparticle disposed on the second side; a nanograting disposed on the bottom surface; and a voltage source configured to provide a voltage bias to the nanograting to suppress surface waves from the first Weyl semimetal nanoparticle to the second Weyl semimetal nanoparticle and to modify surface waves from the second Weyl semimetal nanoparticle to the first Weyl semimetal nanoparticle.
