Mg₂Sn is known as an environmentally-friendly thermoelectric material composed of low-cost elements. We grew 1-inch diameter Mg₂Sn single crystals for application in thermoelectric devices. The samples were grown using the vertical Bridgman method and the VGF method. The crystalline quality of the grown samples was evaluated by the back-reflection Laue method. In this talk, we will report the details of the crystal growth and the crystallographic evaluation of the single crystal samples.
