Why Is Gallium Nitride Used in Power Electronics? Are There Any Alternatives Available?

There are a number of properties that one would wish from a power electronic device:If you look at all the materials that possess semiconducting properties diamond is at the top. The problem is how to get there. Germanium was the 1st material used to create a semiconducting device and as crystal growth tech and doping tech progressed, Silicon became a possibility.We are now in an annoying place. We have the technology to grow Silicon Carbide crystals BUT the yield is low, really low but we have also reach a point where we cannot realise an increase in power density via silicon alone.Gallium Nitride is a stepping stone until SiC process improvements are realised.

Equally there is only a couple of switching types that have been successfully doped and even then they are at low current -> low power.

I'm preparing for a seminar related to variable gain amplifier. I read that GaN/AlGaN are used. I wish to know why they specifically use them.
