“…To shed light into the phonon-drag mechanism at the fundamental level, we used the theory first developed by Bailyn 53 and then adapted to 2DES systems by Cantrell and Butcher [39][40][41][54][55][56] , based on the Boltzmann Transport Equation (BTE) 57 for coupled electrons and phonons. To make calculation affordable, we describe the 2DES electronic structure by an anisotropic effective mass modeling (previously used for a series of oxides 33,[58][59][60][61] ) and the acoustic phonon frequencies by a simple linear dispersion.…”

The thermoelectric power of the two-dimensional electron system (2DES) at the LaAlO3/SrTiO3 interface is explored below room temperature, in comparison with that of Nb-doped SrTiO3 single crystals. For the interface we find a region below T =50 K where thermopower is dominated by phonon-drag, whose amplitude is hugely amplified with respect to the corresponding bulk value, reaching values ∼mV/K and above. The phonon-drag enhancement at the interface is traced back to the tight carrier confinement of the 2DES, and represents a sharp signature of strong electronacoustic phonon coupling at the interface.

Nonlinear thermoelectric efficiency of superlattice-structured nanowires

We theoretically investigate nonlinear ballistic thermoelectric transport in a superlattice-structured nanowire. By a special choice of nonuniform widths of the superlattice barriers-analogous to antireflection coating in optical systems-it is possible to achieve a transmission which comes close to a square profile as a function of energy. We calculate the low-temperature output power and power-conversion efficiency of a thermoelectric generator based on such a structure and show that the efficiency remains high also when operating at a significant power. To provide guidelines for experiments, we study how the results depend on the nanowire radius, the number of barriers, and on random imperfections in barrier width and separation. Our results indicate that high efficiencies can indeed be achieved with today's capabilities in epitaxial nanowire growth.
