Thermal Conductivity of Indium Phosphide-Based Superlattices. Huxtable, S. T., Majumdar, A., Shakouri, A., Labounty, C., Fan, X., Abraham, P., Chiu, Y. J., & Bowers, J. E. *Microscale Thermophysical Engineering*, 4:197-203, July 1, 2000, 2000. Paper abstract bibtex Semiconductor superlattice structures have shown promise as thermoelectric materials for their high power factor and low thermal conductivity. While the power factor of a superlattice can be controlled through band gap engineering and doping, prediction and control of thermal conductivity has remained a challenge. The thermal conductivity of three different InP/InGaAs superlattices was measured to be between 4 and 9 W/m-K from 77-320 K using the 3! method. Although the thermal conductivity of InP is an order of magnitude higher than that of InGaAs, we report the intriguing observation that as the fraction of InP is increased in InP/InGaAs superlattices, the thermal conductivity decreases. For one superlattice, the thermal conductivity was even below that of InGaAs. These observations are contrary to predictions of effective thermal conductivity by the Fourier law.
