Abstract

We performed Monte Carlo simulations on the electron and phonon transport properties of Si nanowires with constant widths and of nanowires modulated by a constriction. We discuss and compare the transport properties and the thermoelectric efficiency in the nanowires. An overall figure of merit (ZT) enhancement is predicted compared to the corresponding non-modulated nanowires. The ZT enhancement in thick, modulated nanowires has been found comparable to that in thin, non-modulated nanowires.
