The synthesis of polycrystalline Cd3As2, a 3D Dirac Semi Metal (DS) was carried out by Gohil S. Thakur, Zeba Haque and Ashok K. Ganguli at Department of Chemistry, IIT Delhi and the point contact Andreev reflection spectroscopic measurement was done by Dr. Goutam Sheet and his students of IISER Mohali. A 3D DS is a bulk analogue of graphene and has a linear dispersion along all the three momentum directions. These materials have intriguing electronic properties and can be related to other exotic states through quantum phase transitions. Cd3As2 is itself not a superconductor nor the Ag tip used for point contact measurements, but we observesuperconductivity with an onset transition temperatureTc ~ 6 K. This is a unique phenomenon of observing superconductivity at mesoscopic point contacts between pure silver metal (Ag) and Cd3As2. The reason for this unconventional superconductivity is due to the injection of electrons by the Ag tip into the Cd3As2 and creating a superconducting region at the mesoscopic contact. Thus our discovery of superconductivity in a 3D Dirac semimetal provides an ideal case to study topological systems. The present work is published in Nature Materials, 2016, 15, 32-37.
