Gallium nitride is a semiconducting compound made up of gallium and nitrogen. It's most notable for having a wider band gap than silicon—giving it a larger range of energy states that are impossible for an electron to take. While silicon has a band gap of 1.2eV, gallium nitride comes in at 3.4eV. This makes GaN a "wide bandgap semiconductor ...
