And yet wide-bandgap technologies still have fundamental weaknesses. The newer materials, known as wide-bandgap semiconductors, are taking over these and other power-electronics applications because they offer many superior characteristics. And if you’ve purchased a wall charger lately for your smartphone or laptop, chances are good that it uses gallium nitride. Silicon carbide is now the semiconductor of choice for the inverters and chargers in electric vehicles, for example. After decades of domination by silicon, two newer materials-silicon carbide and gallium nitride-have begun taking over multibillion-dollar markets. ![]()
