      abstract     = {Bi2Te3 and CoSb3 based nanomaterials were synthesized and
                      their thermoelectric, structural, and vibrational properties
                      analyzed to assess and reduce ZT-limiting mechanisms. The
                      same preparation and/or characterization methods were
                      applied in the different materials systems.
                      Single-crystalline, ternary p-type Bi15Sb29Te56, and n-type
                      Bi38Te55Se7 nanowires with power factors comparable to
                      nanostructured bulk materials were prepared by
                      potential-pulsed electrochemical deposition in a
                      nanostructured Al2O3 matrix. p-type Sb2Te3, n-type Bi2Te3,
                      and n-type CoSb3 thin films were grown at room temperature
                      using molecular beam epitaxy and were subsequently annealed
                      at elevated temperatures. This yielded polycrystalline,
                      single phase thin films with optimized charge carrier
                      densities. In CoSb3 thin films the speed of sound could be
                      reduced by filling the cage structure with Yb and alloying
                      with Fe yielded p-type material. Bi2(Te0.91Se0.09)3/SiC and
                      (Bi0.26Sb0.74)2Te3/SiC nanocomposites with low thermal
                      conductivities and ZT values larger than 1 were prepared by
                      spark plasma sintering. Nanostructure, texture, chemical
                      composition, as well as electronic and phononic excitations
                      were investigated by X-ray diffraction, nuclear resonance
                      scattering, inelastic neutron scattering, Mössbauer
                      spectroscopy, and transmission electron microscopy. For
                      Bi2Te3 materials, ab-initio calculations together with
                      equilibrium and non-equilibrium molecular dynamics
                      simulations for point defects yielded their formation
                      energies and their effect on lattice thermal conductivity,
                      respectively.pssa201532614-gra-0001Current advances in
                      thermoelectric Bi2Te3 and CoSb3 based nanomaterials are
                      summarized. Advanced synthesis and characterization methods
                      and theoretical modeling were combined to assess and reduce
