Notes from a presentation I attended for extra credit that never counted:
Quote:
Srabanti Chowdury
Silicon is plateauing out. Over 10% of the energy generated is lost in inefficient power conversion, greater than the amount generated by solar, wind, and hydro combined, costing more than $40 billion a year, and requires 500 coal power plants. Toyota wanted to find a more efficient conductor to eliminate the cooling system. GaN is bio compatible and non-toxic, piezoelectric, pyroelectric, wide and direct bandgap and GaN LED are already well-developed. GaN is 10x better than normal silicon and 3-4x better than high-whatever Si. Forty percent of the volume of an inverter or LED driver are the magnetics, which GaN reduces.

Except you found something about SiC.
