A new semiconductor with record-high thermal conductivity
(PHYSorg.com Physics)

Scientists at UCLA, for the first time, experimentally realized a new compound single crystal, boron arsenide (BAs) and explored its thermal conductivity limit when crystals are free of defects. They observed the highest isotropic thermal conductivity, 1300 W/mK, beyond all common metals and semiconductors. This study established a new benchmark thermal materials that could potentially revolutionize thermal management technologies in electronics and photonics. This work is reported in the paper `Experimental Observation of High Thermal Conductivity in Boron Arsenide,` published online this week in Science.
