Pretty good article for the new york times non-technical audience. Power electronics is becoming and will become ever more important with everything around us getting electrified and silicon carbide and gallium nitride will become more important within it. Couple of things that I do not agree with: I am not sure whether the silicon shortage has really helped adoption of wide bandgap semiconductors. I think the answer is maybe yes for the cheaper gallium nitride, probably not for silicon carbide. Silicon carbide is arguably in bigger shortage than silicon. And also I would not get excited about the new shiny things like diamond and gallium oxide. In this field it takes a lot of time to bring a new thing online. Customers tend to have very stringent reliability requirements. And bringing production to the quality and profitability levels of silicon carbide and gallium nitride will require a lot of investment over many years.
