Growth and characterization of a novel 2D Sn-based single crystal material*

The discoveries of various van der Waals compounds with diverse functionalities have offered great opportunity for two-dimensional (2D) materials research. Here, we report the growth and characterization of the single crystals of a new tin phosphide compound. This compound crystalizes in a layered, van der Waals-type crystal lattice structure and exfoliates easily. The electronic transport characterizations reveal metallic transport properties with large, linear magnetoresistance at low temperatures. Our findings provide a new Sn-based metallic compound for 2D material research.
