Single crystal diamond nanowires with a size of hundreds of micrometers have the potential to solve the problem of "directional heat dissipation" in electronic devices.

According to the Beijing High Pressure Science Research Center, researcher Li Kuo and Zheng Haiyan's team, in collaboration with research teams from Tsinghua University and other institutions, have made a new breakthrough in the research of diamond nanowires. The related paper was recently published in the international journal "Chem". Corresponding author Li Kuo introduced that through high-pressure annealing technology, single crystal diamond nanowires with a size of hundreds of microns were successfully prepared using 1-naphthalenic acid as the raw material. This single crystal material exhibits nearly zero axial compression rate and extremely strong thermal conductivity anisotropy, and is expected to be used in the next generation of high-performance nano-electronic devices and other fields.
