Cross-plane Seebeck coefficient in superlattice structures in the miniband conduction regime
We have studied experimentally and theoretically the cross-plane Seebeck coefficient of short period InGaAs/InAlAs superlattices with doping concentrations ranging from 2x10(18) up to 3x10(19) cm(-3). Measurements are performed with integrated thin film heaters in a wide temperature range of 10-300 K. It was interesting to find out that contrary to the behavior in bulk material the Seebeck coef...
متن کاملCross-Plane Seebeck Coefficient Anomaly in a High Barrier Superlattice
We have measured the cross-plane Seebeck coefficient of short period InGaAs/InAlAs superlattices with 5nm wells and 3nm barriers with different doping concentrations. Contrary to the behavior of conventional bulk III-V materials, the Seebeck coefficient did not decrease monotonically with increasing doping concentration. A detailed numerical calculation based on semi-classical Boltzmann transpo...
متن کاملCross-plane Seebeck coefficient and Lorenz number in superlattices
Low dimensional and nanostructured materials have shown great potential to achieve much higher thermoelectric figure of merits than their bulk counterparts. Here, we study the thermoelectric properties of superlattices in the cross-plane direction using the Boltzmann transport equation and taking into account multiple minibands. Poisson equation is solved self-consistently to include the effect...
متن کاملCan the Seebeck Coefficient Identify Quantum Interference in Molecular Conduction?
We look for manifestations of quantum interference effects in the Seebeck coefficient of a molecular junction, when the electronic conductance exhibits pronounced destructive interference features due to the presence of quasi-degenerate electronic states, which differ in their spatial symmetry. We perform our analysis by considering three separate limits for electron transport: coherent, fully ...
متن کاملPage 1 Measurement of Seebeck coefficient perpendicular to SiGe superlattice
Seebeck coefficient is one of the key parameters to evaluate the performance of thermoelectric coolers. However, it is very difficult to directly measure Seebeck coefficient perpendicular to thin film devices because of the difficulty of creating a temperature gradient and measuring localized temperature and voltage change simultaneously. In this paper, a novel method is described and it is use...
