 In this study, researchers observed the phenomenon of phonon-poiser flow in a graphite ribbon up to a temperature of 90 Kelvin. This was done using a micro-scale experimental platform and a kinetic theory model based on first principles. The results suggest that phonons can be used as a means of heat transfer, which could lead to new applications such as thermal management and energy conversion.
