Single crystal platelets of Cd3As2 having carrier concentrations less than 1024 m−3 have been grown from the vapour in the presence of argon gas and excess cadmium vapour. It is shown that the resistivity and Hall data is consistent with a band model in which there is a direct band-gap atk=0 of approximately 0.38 eV and an indirect zero band-gap. It is suggested that the large electron carrier concentrations usually present in Cd3As2 result from anti-structure disorder.

Thickness-dependent quantum oscillations in Cd3As2 thin films
Cd3As2 is a new kind of three-dimensional (3D) Dirac semimetal with extraordinary carrier mobility, which can be viewed as ‘3D graphene’. Theory predicts that Cd3As2 can be driven into a quantum spin
