IBM builds first fully functional graphene ic
IBM researchers have used mainstream silicon CMOS manufacturing processes to fabricate and test the world's first multi-stage graphene rf receiver.
Described as the most sophisticated graphene circuit to date, the fully functional device has so far been used to transmit a text message with the letters 'I-B-M' in it.
The researchers claim the receiver offers a 10,000x improvement in performance compared to previously reported graphene ics, and say it could allow devices such as smartphones, tablets and wearable electronics to transmit much faster data loads in a more cost effective and power efficient way.
"This is the first time that someone has shown graphene devices and circuits to perform modern wireless communication functions comparable to silicon technology" said Supratik Guha, director of physical sciences, IBM Research.
