Prof. Kuball explained:
"Most semiconductor electronics heat up when used. The hotter they get, the greater the rate at which they degrade, and their performance diminishes. As we rely more and more upon our electronic devices, it becomes increasingly important to find materials with high thermal conductivity which can extract waste heat.
"Boron Nitride is one such material which was predicted to have a thermal conductivity of 550 W/mK, twice that of copper. However, all measurements to date seemed to show its thermal conductivity was much lower. Excitingly, by making this material 'ultra-pure', we have been able to demonstrate for the first time its very high thermal conductivity potential."
Professor Kuball said the next step was to start making active electronic devices from Boron Nitride, as well as integrating it with other semiconductor materials.
"In demonstrating the potential of ultra-pure Boron Nitride, we now have a material that can be used in the near future to create high performance, high energy efficiency electronics."
"The implications of this discovery are significant. Certainly, our reliance on electronics is only going to increase, along with our use of mobile phones and adoption of electric cars. Using more efficient materials, like Boron Nitride, to satisfy these demands will lead to better performance mobile phone communication networks, safer transportation and ultimately, fewer power stations."
