Graphene has long-held notions of grandeur over its current silicon overlord, but a few practical issues have always kept its takeover bid grounded. Samsung, however, thinks it's cracked at least one of those -- graphene's inability to switch off current. Previous attempts to use graphene as a tra...

Graphene's greatness comes from its flexibility, both figurative -- you can make everything from transparent speakers to stain resistant pants with the stuff -- and literal. And now researchers in Korea have given us another pliable graphene product by creating a stretchy transistor from the carb...

IBM might be cautious about touting graphene as a a silicon killer, but that hasn't stopped it from pushing the production of ever faster graphene transistors. With the recent demonstration of a 155GHz graphene transistor, the firm successfully outdid its previous record-setting efforts, which produ...

It's just been a little over a week since IBM researchers announced that they managed to open up a bandgap for graphene-based field-effect transistors, but they're now already back to show off what that's made possible: a 100GHz graphene transistor. What's more, this latest record-setting transistor...

Graphene transistors have long been touted as the next big thing to deliver a true leap in electronics of all sorts, but there's been a few considerable limitations holding them back from fully replacing silicon. IBM now says it's managed to overcome one of the biggest hurdles, however, and has anno...
