Thin-film Dirac semimetal review article

Iolanda DiBernardo reviewed the development of Na3Bi as a topological electronic material.

The physics of Dirac semimetals (“3d graphene”) is introduced, and the results from the last half decade are tied together in one narrative, in particular our work at Monash demonstrating that Na3Bi grows directly on insulators, and that indeed an electric field will open a topological gap, two key ingredients to achieving a working “topological transistor”.
