Treborjim: I never grasped the transistor hole theory so the inside workings of a POET are totally beyond me.
Suffice to say that normally "holes" (whatever that might be) in gallium arsenide transistors move much too slow to make GaAs a viable replacement for silicon-based digital technology (CMOS).
However, the Good Doctor has found a way to make those "holes" much faster.
This is fundamental to POET! If this wouldn't work, we could forget about all that POET stuff.
