Vapor-phase synthesis and magnetoresistance of (Cd1-xZnx)3As2 (x=0.007) single crystals
Abstract
We report a highly anisotropic magnetoresistance of (Cd0.993Zn0.007)3As2 single crystals, which were synthesized by the vapor-phase growth. Scanning electron microscopy and electron diffraction data confirm the high crystalline quality of obtained samples. Studied samples exhibit specific features such as octahedral nuclei growth and step-like morphology of the surface formed by {112} planes. The giant anisotropic magnetoresistance and Shubnikov-de Haas oscillations were observed at low temperatures. The results suggest the existence of the Dirac semimetal phase in (Cd1-xZnx)3As2 solid solution with low zinc content. Thus, the observed magnetoresistance anisotropy is partially attributed to the chiral anomaly.
