"Phase tantalum nitride achieved a thermal conductivity of about 1,110 watts per meter-kelvin, about three times higher than copper's 400 watts per meter-kelvin."
"In this structure, the researchers found that both electrons and packets of vibrational energy called phonons encountered less resistance compared with conventional metals."
"The material also revealed a previously unexplored strategy to boost metallic heat conduction, which could lead to advancements in cooling technologies."
Phase tantalum nitride has been discovered to have a thermal conductivity of about 1,110 watts per meter-kelvin, significantly surpassing copper's 400 watts per meter-kelvin. This new material operates through a unique atomic arrangement in a highly ordered crystal lattice, allowing both electrons and phonons to conduct heat with less resistance. The findings suggest that tantalum nitride could complement or replace copper in various applications, marking a breakthrough in metallic heat conduction.
