"Theory of enhanced thermoelectric performance in strongly correlated 
multilayered nanostructures"


Abstract

  We illustrate how the electronic charge reconstruction near the 
interfaces of metal/strongly-correlated barrier/metal devices  can lead 
to a significant  enhancement of the thermoelectric  response due to 
the breaking of particle-hole symmetry.  We show how one can achieve 
effective Seebeck coefficients larger than 150 μV/K and effective 
electronic figures-of-merit ZT higher than 1.  Our theory shows that 
electronic thermoelectric transport properties can be significantly 
enhanced from inhomogeneities created by the rearrangement of charge 
near the interfaces, and that bulk figures-of-merit cannot generically 
be employed to determine the figure-of-merit of a multilayered  
nanostructure.
