re: IBM researchers to report carbon feats at IEDM

The Silicon atom is about .24 nm. Carbon is about .14 - a bit more than half as big. It looks like there's still some room to make transistors smaller than the sub-10 nm. Not much though. I don't see any solids with a diameter smaller than carbon so that may be it for the traditional binary logic building block. It's getting close to time to look for something that will give a couple more states from the same size device.

Feynman said that there is plenty of room at the bottom. We are hitting the bottom and it is full of surprises. Graphene, CNT, Nanowires, variation of FinFET will compete for the lower technology nodes for sure.

ha ha. Readers have found out so many misspell in EETimes blogs in recent times. Hope it will improve.

Is "grapheme" a derivative of "graphene"? :)

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
