Awesome article Chris, thanks!

One question:

Hasn't POET already done most, if not all of these things?

Some would argue POET does the fab process better, depending on what "relatively minor" means, amongst other items.

Are we advertising that fact?

very low leakage currents, thanks to the insulating layer beneath the devices; relatively minor adjustments to the foundry processes, because the challenges of introducing new materials are shifted to the substrate supplier; and tremendous freedom for the circuit designer to select the size and position of the transistors.
