POET needs to step in here and quantify just how much of a lie this is. They are no where near the first to do what they are claiming they have done. . POET did this way long ago!
Chu concluded, “GaN CMOS IC was considered difficult or impossible, due to the challenge in making P-channel transistor and integrating an N-channel transistor.Our recent work opened up the possibility of making GaN CMOS IC’s.”
