Enhanced figure of merit in nanostructured (Bi, Sb) 2 Te 3 with optimized composition, prepared by a straightforward arc-melting procedure
F Serrano-Sánchez, M Gharsallah, NM Nemes +5
Sb-doped Bi2Te3 is known since the 1950s as the best thermoelectric material for near-room temperature operation. Improvements in material performance are expected from nanostructu…
