Abstract

Quantum dot superlattices and quantum wire arrays have been proposed for thermoelectric applications. Strong improvement of the thermoelectric properties in such structures is expected only if the structure parameters are carefully tuned to achieve desired carrier and phonon transport characteristics. In this paper we present our preliminary results of the modeling-based optimization of Ge/Si QDS for achieving the thermoelectric figure of merit enhancement.
