Researchers discover 3D material that behaves like graphene

Researchers from Oxford, SLAC, and Berkeley Lab have found that cadmium arsenide could yield practical devices with the same extraordinary electronic properties as 2D graphene. The researchers also found that the new “semimetal” material exists in a sturdy 3D form that should be much easier to shape into electronic devices such as very fast transistors, sensors and transparent electrodes.

The results are described in a paper published May 25 in Nature Materials.

There is a quest to find graphene-like materials that are three-dimensional, and thus much easier to craft into practical devices.

Two other international collaborations based at Princeton University and in Dresden, Germany, have also been pursuing cadmium arsenide as a possibility. One published a paper on its results in the May 7 issue of Nature Communications, and the other has posted an unpublished paper on the preprint server arXiv.

The research team also included scientists at Fudan University in Shanghai, the Chinese Academy of Sciences and Diamond Light Source. The work was partially funded by the U.S. Department of Energy Office of Science and the Defense Advanced Research Projects Agency (DARPA) Mesodynamic Architectures program.
