A small transistor that can accurately detect tiny traces of RNA from SARS-CoV-2 could herald a new breed of rapid COVID-19 screening tests (J. Am. Chem. Soc. 2021, DOI: 10.1021/jacs.1c06325).

The idea of replacing silicon with carbon to make computer chips is not new. However, using graphene -- a single layer of carbon atoms arranged in a honeycomb lattice -- wasn't feasible because it is ...

Researchers at Rice University and the University of California, Riverside have taken advantage of another quirk in graphene's arsenal, ambipolarity, to build and test a triple mode transistor, that ...

Electronic engineers at Japan's GNC and AIST research centers have successfully created graphene transistors that are constructed and operated in a way that redefines 50 years of transistor ...

Graphene is hot. The recent Nobel Prize-winning research into graphene is just the tip of the iceberg; researchers around the world have been looking at ways to take advantage of graphene’s structural ...

Researchers in the US have developed a new way of making transistors from graphene – a sheet of carbon just one atom thick. The technique overcomes a major obstacle facing those who want graphene to ...

Scientists at IBM have made the fastest graphene transistor to date. The device operates at frequencies as high as 26 GHz and could find use in wireless communications equipment. A transistor’s ...

The remarkable increases in computer speed over the last few decades could be approaching an end, in part because silicon is reaching its physical limits. But this past December, in a small Washington ...
