Phonon hydrodynamic regimes in sapphire
Takuya Kawabata, Kosuke Shimura, Yuto Ishii +7
When an ideal insulator is cooled, four regimes of thermal conductivity are expected to emerge one after another. Two of these, the Ziman and the Poiseuille, are hydrodynamic regim…
Phonon hydrodynamics and ultrahigh-room-temperature thermal conductivity in thin graphite
Yo Machida, Nayuta Matsumoto, Takayuki Isono +1
Allotropes of carbon, such as diamond and graphene, are among the best conductors of heat. We monitored the evolution of thermal conductivity in thin graphite as a function of temp…
Observation of Poiseuille Flow of Phonons in Black Phosphorus
Yo Machida, Alaska Subedi, Kazuto Akiba +5
The travel of heat in insulators is commonly pictured as a flow of phonons scattered along their individual trajectory. In rare circumstances, momentum-conserving collision events…
