Low-Temperature Synthesis of Thermoelectric Group 14 and Group 15 Chalcogenide Nanoparticles by Thermal Decomposition of Tailor-Made Metal Organic Precursors (MOPs) in Ionic Liquids (ILs)

  • Develop new reactive polynuclear IL precursors for the synthesis of phase pure nanomaterials of group 14 and group 15 chalcogenides (SnE, PbE, Sb2E3, Bi2E3, (SbxBi1-x)2E3, (BixSb1-x)2 (TeySe1-y)3; E = Se, Te)
  • Incorporate heavy metal dopants (Ag, In, Tl) to improve TE properties
  • Synthesize NPs using alternative ILs of promising cation/anion combinations to increase the solubility of MOPs and lower the binding affinity of the IL
  • Characterization of NPs via PXRD, SEM, TEM, and EDX
