Crystal growth and magneto-transport behavior of PdS1−δ

PdS is theoretically proposed to novel topological material with eight-band fermions. Here, PdS1−δ crystals were successfully grown from KI as solvent by modified flux method. The single crystalline quality and compositional homogeneity of grown PdS1−δ are characterized by X-ray diffraction and energy dispersion spectroscopy. Temperature dependent electrical transport property of PdS1−δ demonstrates a semiconductor-like behavior. Analysis of temperature-dependent resistance indicates that there is variable-range-hopping behavior at low temperature. The clear negative MR of PdS1−δ single crystals is measured at the low temperature (<30 K), which may be ascribed to the interaction between conducting carriers and localized moments. however, the magneto-transport results have not shown the clues of topological feature of PdS.
