The bulks of polycrystalline SnSe materials were successfully prepared by the mechanical alloying (MA) and spark plasma sintering (SPS) method. X-ray powder diffraction analysis showed that pure Sn and Se powders were synthesized into the SnSe phase by MA, and after SPS under 30–120 MPa, the single phase bulks of SnSe materials were successfully prepared. Scanning electron microcopy images displayed...
