Thanks Oogee.
It looks like without having to get to technical and complicated with holes and stuff it all comes down to this statement
"The reason why POET can outperform CMOS with seriously different feature sizes comes down to heat. POET's GaAs transistors don't have an issue with waste heat and so the clock frequency can be much higher. This is something we knew already, but I thought I'd confirm it."
My thought, it seems like the speed of electrons slow down with to much heat ,inversely proportional at a certian temperture and beyond I suppose. GaAs stays much cooler then Si with load.
So we can have both faster and more efficiency( much less power usage) Or cheaper and faster with decrease in size which is what it's all about.
I like the fact that it has become clear that 100nm was a response to a suitor
