摘要：

We report on measurements of thermal conductivity of a series of eight GaAs/AlAs superlattices. A picosecond optics technique was used to determine the conductivity kappa. The conductivity in all samples was found to decrease monotonically throughout the temperature range 100-375 K. There was a general decrease in kappa c with reduction in the superlattice period, and for the superlattices with the shortest period kappa at room temperature was reduced by a factor of 10 compared to bulk GaAs.
