Is gallium nitride (GaN) the silicon of the future?

When comparing GaN and silicon, the bandgap is a good place to start. GaN's bandgap is 3.4 eV, whereas silicon has a value of just 1.12 eV. This means GaN semiconductors can sustain higher voltages and survive higher temperatures than silicon MOSFETs. The current can travel faster through GaN semiconductors, ensuring greater efficiency and
