Magnetotransport and Quantum Oscillation Phenomena in Dirac Semimetal Na3Bi — •Mohammad Pakdaman, Alimamy Bangura, Claus Mühle, and Hidenori Takagi — Max-Planck-Institut für Festkörperforschung, Heisenbergstrasse 1, D-70569 Stuttgart, Germany
Three dimensional Dirac semimetals are a three dimension analogue of Graphene where the conduction band and valance band touch at discrete points in reciprocal space with linear dispersion. In this class of materials Na3Bi has a uniquely simple band structure compared to other example discovered so far. A consequence of this unique band structure is the realization of unusual electronic properties that are predicted to be manifest in the transport properties. In order to probe the exotic electronic properties of this material, the magnetotransport measurement have been done on single crystal of Na3Bi. The results were compared to the ab initio calculations and predictions of the physical properties for this recently predicted state of matter, and these experiments give further evidence for the realisation of this exotic state of matter.
