UCLA Scientists Discover New Material for Superior Heat Management

4/18/2026

Summary

Story summary

UCLA scientists report that theta-phase tantalum nitride (?-TaN) has about 1,100 W/mK thermal conductivity, nearly three times copper.
The work, published in Science, could transform heat management in electronics by reducing overheating.
Theta-TaN's atomic structure minimizes electron–phonon interactions, enabling efficient heat dissipation.
Yet production costs and integration into existing systems pose practical challenges.
If scaled, ?-TaN could enhance performance and longevity of devices in data centers and AI.
