Researchers at IBM demonstrated a radio-frequency graphene transistor with the highest cut-off frequency achieved so far for any graphene device - 100 billion cycles/second (100 GigaHertz).
Graphene is a single atom-thick layer of carbon atoms bonded in a hexagonal honeycomb-like arrangement. IBM said this two-dimensional form of carbon has unique electrical, optical, mechanical and thermal properties and its technological applications are being explored intensely.
The wafer-scale, epitaxially grown graphene transistor was created with processing technology compatible to that used in advanced silicon device fabrication.
IBM said it is noteworthy that the frequency performance of the graphene device already exceeds the cut-off frequency of state-of-the-art silicon transistors of the same gate length (~ 40 GigaHertz).

The new chipset lays the foundation for a total capacity of 4 Tbps in a single, half-rack system. Juniper's T Series systems are already capable of supporting true line-rate 100 GE interfaces. The new chipset will further enable the scaling of single chassis systems up to 4 Tbps.



Microsoft will provide cloud computing research projects identified by NSF with access to Windows Azure for a three-year period, along with a support team to help researchers quickly integrate cloud technology into their research. Projects will be awarded and managed by NSF.
