Cubic Boron Arsenide Can Compete Diamond in Thermal Conductivity

Cubic Boron Arsenide Can Compete Diamond in Thermal Conductivity

As per reports, a team of researchers from Boston College and the Naval Research Laboratory have revealed that they have created a new substance that can compete with diamond in thermal conductivity.

Published in the latest issue of the journal Physical Review Letters, the research disclosed that cubic boron arsenide is capable of delivering thermal conductivity as high as that is delivered by diamond. It is learnt that diamond is best known thermal conductor.

However, it is not used widely as it is rare and expensive. In addition, production of high quality synthetic diamond quite difficult and incurs high expenses. This is the reason that researchers are looking for new materials with ultra-high thermal conductivities.

The researchers said that thermal conductivity of cubic boron arsenide is very high. It was found to be about 2,000 Watts per meter per Kelvin at room temperature. That was comparable with that of diamond and exceeded it at higher temperatures.

David Broido, a Professor of physics at Boston College, said the research was an important work and gave new vision towards physics of heat transport in materials. "It illustrates the power of modern computational techniques in making quantitative predictions for materials whose thermal conductivities have yet to be measured", he added.

AR Scorpii is a pair of two stars

Star AR Scorpii is not a single star in the Scorpius constellation as thought earlier. There are two stars that orbit each other every 3.6 hours. A white dwarf and a red giant are about 380 light-years from Earth. They were precisely noticed by multiple telescopes, including the ESO's Very Large Telescope in Cerro Paranal, Chile, and the Hubble...
