Abstract
The class of solid-state systems hosting massless electrons has been recently expanded to include materials with truly 3D conical bands. In my talk, I will review our recent high-field infrared magneto-spectroscopy studies of two such materials : HgCdTe [1,2], tuned to the point of the topological semimetal-semiconductor transition and hosting 3D massless Kane electrons, and Cd3As2 [3], recently reported to be the premier 3D topological Dirac semimetal, which is stable at ambient conditions.
