Previously, when they first reported the material in 2021, I think? https://feng.mech.utah.edu/wp-content/uploads/sites/152/2022...

Still only half the thermal conductivity of diamond. But pretty awesome nonetheless! I hope it's easy to make.

Can we make heat sink out of synthetic diamonds?

Yes, that is a thing.

Also fabricating integrated circuits on a diamond substrate.

"a metallic material called θ-phase tantalum nitride"

> In the form of tantalum nitride that Hu and his colleagues studied, the atomic structure of the crystal lattice lets phonons travel unusually long distances with minimal interference.

Sort of like a thermal (phonon) superconductor.. Maybe there's a true thermal superconductor out there to be discovered...

"Maybe there's a true thermal superconductor out there to be discovered..."

it's called a vacume, and honestly I believe that for heat, thats it, given it's role in physics....

Vacuum? It’s a terrible conductor. Closer to a perfect insulator.
