MIT claims to have found the best possible semiconductor!
Silicon is now at the heart of our daily lives. in our smartphones. In our PV solar panels. However it is not perfect. But this new material that researchers have studied closely could be just that. His name, cubic boron arsenic.

[EN VIDÉO] Is it possible to recycle solar panels? Since 2012, European directives have forced manufacturers of photovoltaic panels to collect and recycle. But is recycling these panels technically feasible? Marion Perrin, an electrochemist, explains, in a video, that the process is no longer any difficulty today.
Silicon is everywhere. in our chips Computers. or in our area Photovoltaic solar panels. However, this semiconductor material is far from perfect. It causes overheating problems. And do not let all the files “grains” loader. brakes for some apps. But looking for Massachusetts Institute of Technology (MIT, US) They now think they’ve found a material that ignores these difficulties. They even refer to arsenide as Boron Cubic (c-BA) of The best semiconductor never found. Even the best possible semiconductor!
some – like are you herefor him electric car – She’s already switched from silicone to silicon carbide. Because, even if its electrical mobility is less, its thermal conductivity is three times higher. The cubic boron arsenic created by MIT researchers has a thermal conductivity 10 times greater than that of silicon. and high mobility of both electrons and “holes” – Their changing positive egos. ‘It could change the rules of the game’comments by Jungwoo Shin, researcher, at A MIT press release.
More locks to break
The problem is that at present, it is still difficult to produce cubic boron arsenide. At least with sufficient quality to allow it to express all these characteristics of interest to researchers. This requires that the material be uniform. Existing methods can only produce irregular cubic boron arsenide.
Another problem: there are still basic properties to make it The designated Si alternative that has not yet been tested. Its long-term stability, for example. “So far, we have not paid much attention to this material.”Zhang Chen, another researcher at the Massachusetts Institute of Technology, said. But now that some of these properties have been revealed, Perhaps we will give it more credit, and thus we will be able to develop methods to describe it better and produce it better. »
