Samsung draws logic-worthy on/off ratio from graphene

Researchers at Samsung’s Advance Institute of Technology have developed a new transistor structure using everyone’s favourite two-dimensional material, Graphene.Despite its wonderful conductivity, electron mobility and so on that make it such an alluring prospect for chip designers bumping into the physical limits of silicon, it has no band gap.

Clever on-off switch for graphene. Transistors next?

The Manchester University team that first isolated graphene has discovered a way of introducing a band gap into the material that makes it a much more promising candidate for building transistors.Graphene is famous for its astonishing list of useful characteristics – especially its conductivity.

Swedish team's graphene mixer opens up THz possibilities

Researchers at Sweden’s Chalmers University have built a CMOS compatible graphene based electronic mixer – a device that combines multiple input signals into one or two composite outputs – that already works at microwave frequencies and could be extended to the terahertz range.Jan Stake, professor of the research team says that the performance of the mixer can be improved by further optimising the circuit, and improving the on-off ratio.

Graphene auditions for lead in Terahertz productions

Two teams of US researchers have got their eye on graphene to advance the state of the art in medical imaging, communications and security screening, thanks to its strong response to the terahertz region of the electromagnetic spectrum.Writing in Nature Nanotechnology, scientists from Lawrence Berkeley National Laboratory and the University of California at Berkeley, explain how nanoribbons of graphene could form the "beginnings of a toolset" for working with terahertz radiation.

Lasers could illuminate band gap for graphene

Graphene: famous for being a Nobel Prize prompting wonder material, and for having no band gap. The lack of band gap means graphene’s future as a possible replacement for silicon has always looked bleak, because a band gap is the property that allows a transistor to be switched on and off.
