Pressure-induced superconductivity in the three-dimensional Dirac semimetal Cd3As2

Understand

The recently discovered Dirac and Weyl semimetals are new members of topological materials.

• Starting from them, topological superconductivity may be achieved, e.g.
• by carrier doping or applying pressure.
• Here we report high-pressure resistance and X-ray diffraction study of the three-dimensional topological Dirac semimetal Cd3As2.
