Atomistic Design of Thermoelectric Properties of Silicon Nanowires

We present predictions of the thermoelectric figure of merit (ZT) of Si nanowires with diameter up to 3 nm, based upon the Boltzman transport equation and ab initio electronic structure calculations. We find that ZT depends significantly on the wire growth direction and surface reconstruction, and w...
