Gallium Nitride: The Future of Semiconductors | Tower …
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 ...

New Generation of Gallium Nitride
Next, a separate layer of aluminum gallium nitride, 15-25 nanometers is made. These two layers, with dielectric passivation adding an insulation layer to the device surface, form the basic transistor layer structure. Metallization layers are then added to make electrical contacts, and to form the transistor drain, gate and further interconnects.
