Abstract / Description:A room-temperature microemulsion synthesis of molecularly capped
bismuth telluride nanoparticles with small (average ca. 2.5 mn)
diameters is reported (see figure). The use of thioglycolic acid
ligands inhibits nanoparticle agglomeration and surface oxidation.
Annealing the nanoparticle films to 350 degrees C yields a Seebeck
coefficient of - 107 mu K-1. The findings are attractive for realizing
of high figure of merit thermoelectric materials via nanostructuring
control over surface chemistry.
