Every week we read about another technology center or consortium starting up. By the time the buildings are built (which cannot be moved), much of the money and kick-off energy have been consumed. How efficient are such centers for getting research done? Is it better just to fund promising projects and allow the investigators to pool resources and share expensive capital equipment?

Natural surface roughness should be enough to tear or break up the graphene film.

So let me make sure I understand the argument - the only thing standing between graphene and some mind boggling new chips is that " at the moment we cannot produce it in a perfect form over large areas". Wake me up when that pipe dream ends.

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.
