Each week we get thousands of tips on new technologies but can't write about all of them. Here's my pick of the cream-of-the-crop of tech advances you'll want to know about but may have missed or don't have to absorb. I'll be writing a weekly blog, called “Brief Takes” we limit ourselves to three paragraphs, so you get the gist, and ask you (please leave a comment) if you want to hear more.
BRIEF TAKE#1: “Carbon Semiconductors Could Extend Moore's Law”
(Source: Rice University)
Carbon is a pure conductor with no bandgap in its native state, but researchers worldwide have been finding ways — such as doping — to turn it into the dream semiconductor that could replace silicon at the end of its roadmap, circa 2028, thus extending Moore's Law indefinitely.
Reachers at Rice University believe they can realize that dream by deforming the edges of carbon nanoribbons, in order to convert them into any type of semiconductor they need. Currently the team is cataloging the types of edge deformations they need to make for different applications. Their technique is pulling them apart with just the right force and at just the right temperature, creating just the right electronic properties they need.
Their technique could also solve the problem of some nanotubes being conducting and some being semiconducting. By applying just the right pulling force and temperature can change their characteristics from conducting to just the right sort of semiconductor, according to Rice.
