Yup... Regular silicon fractures and fails in a big way under high heat. Even silicon carbide can however rarely fail so it needs to be thoroughly tested before being used in a high heat environment to avoid failure down the road (Pun intended). What AEHR does better than anyone else now is allow companies to test large amounts of silicon carbide quickly and inexpensively so ON and therefore TSLA (and other EV companies) can avoid failures.

What’s the Difference Between Silicon Carbide and Silicon? March 23, 2022 Silicon carbide has already contributed significantly toward electromobility and digitization of industrial processes. But what is SiC, how does it differ from traditional silicon, and what makes it an ideal material to accelerate EV goals? Roveendra Paul Thomas Neyer Related To: onsemi electronicdesign.com

SiC has higher electron mobility than Si so it makes for better (lower loss to heat) devices for switching power. Tesla uses an AC motor so you need a switching power supply to convert the DC battery to AC power. That is done best with a switching transistor (probably a power MOSFET but I'm decades out of the industry so the terms may be different.) Tesla said they were eliminating 75% of their SiC from their cars... my thought is they might have a DC motor under development as an easy way to achieve this, especially since DC motors are more efficient than AC.
