内容記述 We compare Bi_2Te_3 powders prepared by conventional ball milling to powders milled in supercritical carbon dioxide (scCO_2). We demonstrate that scCO_2 milling overcomes size-reduction limitations reported for conventional milling. XRD and TEM reveal nanograins with smaller average sizes (< 10 nm) and narrower grain size distributions in the scCO_2 milled case. scCO_2 milling also preserves the crystallinity and shows less oxidation than conventional milling. This is the first report of Bi_2Te_3 with a sub-10 nm grain size whilst conserving high quality crystallinity, made using a top-down approach. Our study offers a route for developing unprecedentedly fine bulk nanostructured Bi_2Te_3-based thermoelectric materials.
