“Silicon is great, apart from when you put a high current through it,” he says. “That’s why we’re interested in silicon carbide, which allows us to push the limits.” Above: GE Research announced that its engineers would collaborate with the United States Army Research Laboratory to take the stalwart silicon carbide chips in those electric vehicles to the next level.
Silicon Carbide SiC Material Properties
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.

Graphene band gap heralds new electronics | Research | …
In this method, a silicon carbide (SiC) substrate is heated to temperatures of 1360 C, at which point it begins to decompose and form graphene layers. The researchers found that the first of these layers, normally called the buffer layer, forms a band gap greater than 0.5 eV, because of the highly periodic way it bonds to the SiC substrate.
