- A new metallic material called β-phase tantalum nitride has achieved a thermal conductivity of about 1,110 watts per meter-kelvin, approximately three times higher than copper's 400 watts per meter-kelvin.
- The material's atomic structure features a continuous, highly ordered crystal lattice, which reduces resistance for both electrons and phonons, enabling superior heat conduction.
- This discovery reveals a previously unexplored strategy where phonons travel long distances with minimal interference, unlike in ordinary metals where they are frequently disrupted.
- The findings could have a substantial impact on thermal management in electronics, data centers, and energy systems, especially with the growing demands of artificial intelligence.
- The breakthrough challenges long-standing assumptions in materials physics, prompting scientists to reconsider other assumed fundamental limits.
