Crystal growth of Dirac semimetal ZrSiS with high magnetoresistance and mobility.

ABSTRACT: High quality single crystal ZrSiS as a theoretically predicted Dirac semimetal has been grown successfully using a vapor phase transport method. The single crystals of tetragonal structure are easy to cleave into perfect square-shaped pieces due to the van der Waals bonding between the sulfur atoms of the quintuple layers. Physical property measurement results including resistivity, Hall coefficient (R_H), and specific heat are reported. The transport and thermodynamic properties suggest a Fermi liquid behavior with two Fermi pockets at low temperatures. At T = 3 K and magnetic field of Hǁc up to 9 Tesla, large magneto-resistance up to 8500% and 7200% for Iǁ₍₁₀₀₎ and Iǁ₍₁₁₀₎ were found. Shubnikov de Haas (SdH) oscillations were identified from the resistivit
