IBM Research on Friday announced that it has demonstrated a radio-frequency graphene transistor with the highest frequency so far: 100GHz.

Graphene is a special form of graphite, consisting of a layer of carbon atoms packed in honeycomb lattice. In a nutshell, graphene is like "atomic scale chicken wire." Graphene's properties could lead to faster transistors.

IBM's paper, which is being published in Science, details how the latest graphene breakthrough could enable new communications devices and electronics. The paper was penned by Phaedon Avouris, IBM Fellow and manager of the company's nanometer-scale science and technology research team.

Outcry over iPhone 'Error 53' and bad USB Type-C cables

Be careful when replacing parts. Poorly made cables can fry a laptop, and iPhones will stop working if the Touch ID button is repaired outside of Apple. It's a lesson some are learning the hard way.
