Quantum confined semiconductors composed of heavy elements are candidates for materials that exhibit improved thermolelectric figure of merit. The solution phase synthesis of bismuth telluride nanoparticles has been accomplished in the presence of a library of thiols as the capping ligand. These crystalline nanostructures range in size between ~20 to 60 nm with a relatively narrow size dispersity. Size and shape of the resulting nanostructures has been investigated as a function of chain length of the thiol and temperature.
