“In silicon carbide, the silicon and carbon really want to be paired together; they want to be 50 percent carbon and 50 percent silicon,” she says. However, when her team ran simulations and also imaged the grain boundaries, the carbon concentration was only 45 percent at the boundaries. “The chemistry was just really off,” she says.
