Query: Enhanced Thermoelectric ZT in the Tails of the Fermi Distribution via
  Electron Filtering by Nanoinclusions -- Model Electron Transport in
  Nanocomposites   Silicon carbide nanoparticles with diameters around 8 nm and with narrow size
distribution have been finely mixed with doped silicon nanopowders and sintered
into bulk samples to investigate the influence of nanoinclusions on electrical
and thermal transport properties. We have compared the thermoelectric
properties of samples ranging from 0-5% volume fraction of silicon carbide. The
silicon carbide nanoinclusions lead to a significant improvement in the
thermoelectric figure of merit, ZT, largely due to an enhancement of the
Seebeck coefficient. A semiclassical Boltzmann transport equation is used to
model the electrical transport properties of the Seebeck coefficient and
electrical conductivity. The theoretical analysis confirms that the
enhancements in the thermoelectric properties are consistent with the energy
selective scattering of electrons induced by the offset between the silicon
Fermi level and the carbide conduction band edge. This study proves that
careful engineering of the energy-dependent electron scattering rate can
provide a route towards relaxing long-standing constraints in the design of
thermoelectric materials.
