He attached a custom copper heatsink to a section of the heat spreader, which had been carefully milled flat to provide the best thermal contact. [Zach] used a fancy boron nitride heat transfer ...

Researchers from Pohang University of Science and Technology (POSTECH) and the University of Montpellier have successfully synthesized wafer-scale hexagonal boron nitride (hBN) exhibiting an AA ...

modes in hexagonal boron nitride (hBN). The study shows that these hybrid light–vibration modes can transfer energy at rates far exceeding conventional phonon–phonon conduction. Image Credit ...
