Boron arsenide crystals can dissipate the heat generated in electronic devices

The original article and the "full" article don't actually list any numbers. Looks like the performance is 1000 ± 90 W/m/K [0]

For comparison, a traditional high-end thermal paste may have 10 W/m/K, a liquid-metal thermal paste is up to 73 W/m/k [1]. Copper is 385, Aluminum is 200, Diamond is 1000.

> Diamond is 1000.

The paper itself gives diamond as 2200 and isotopically pure diamond has even higher conductivity.

The question is whether it's any easier to manufacture than a diamond layer. Edit: The paper claims as much.
