Abstract

A surfactant-free solution methodology, simply using water as a solvent, has been developed for the straightforward synthesis of single-phase orthorhombic SnSe nanoplates in gram quantities. Individual nanoplates are composed of (100) surfaces with (011) edge facets. Hot-pressed nanostructured compacts (E_g≈0.85eV) exhibit excellent electrical conductivity and thermoelectric power factors (S²σ) at 550K. S²σ values are 8-fold higher than equivalent materials prepared using citric acid as a structure-directing agent, and electrical properties are comparable to the best-performing, extrinsically doped p-type polycrystalline tin selenides. The method offers an energy-efficient, rapid route to p-type SnSe nanostructures.
