Cubic Boron Arsenide’s Unique Semiconducting Properties (MIT)


New research claims cubic boron arsenide could be a “game-changing” semiconductor with a “very high mobility for both electrons and holes,” according to this MIT article.

“Heat is now a major bottleneck for many electronics,” says Shin, the paper’s lead author. “Silicon carbide is replacing silicon for power electronics in major EV industries including Tesla, since it has three times higher thermal conductivity than silicon despite its lower electrical mobilities. Imagine what boron arsenides can achieve, with 10 times higher thermal conductivity and much higher mobility than silicon. It can be a gamechanger,” said Shin.
