Abstract Se nanowires are one of the chalcogenide nanostructures that have attracted interest in various fields of research because of their unique characteristics. The Se nanowires were fabricated from bulk SnSe crystals by an organic acid-assisted chemical transformation process. We found that the concentration of the organic acid during the reaction is critical to control the morphology of the final product. Se nanowires with ∼40 nm diameter and ∼1 μm length were obtained after the transformation, and the reaction mechanism for the chemical transformation was proposed. Moreover, the effect of the Se nanoparticles in SnSe on its thermoelectric behavior was also investigated and discussed. The fabrication method and materials reported in this study will open up new possibilities for various applications with excellent performance.
