IBM develops one of its kinds Graphene integrated circuit

radio frequency signals, mix them and eventually, transmit a different frequency. Already used in radios and phones, this mixer powered the analog television sets of the pre-digital days.

Graphene in the IBM integrated circuit will operate at a record 10 Ghz capacity withstanding high temperatures. The size of its circuit is less than a square millimeter thereby promising high electron mobility and in turn high device performance. It's a long way to a full-proof triumph yet, as graphene is prone to certain drawbacks like its inability of instant switch off - a key requirement for digital information transfer. IBM's pioneering effort nevertheless is a big leap forward in the amazing graphene revolution.
