Will Gallium Nitride Electronics Change the World?

Silicon may be at the heart of most gadgets, but it's not the only semiconductor around. Gallium nitride has been getting a lot of attention recently for its electrical properties, which outperform silicon in a lot of areas. Gallium nitride has the potential to revolution power systems, including solar, electric vehicles, and even phone chargers. Beyond that, it's finding uses in the mobile industry, and could even be used to build ultra-fast processors.

But how feasible is any of that, and even if it's possible, how long will it take?
