Ballistic thermoelectricity in double-bend nanowires
Abstract
We investigate ballistic thermoelectric transport in double-bend nanowires. The geometric confinement induces quantum interference effect, which results in large Seebeck coefficient. The Seebeck coefficient (both the sign and the amplitude) is tunable by changing the structural parameters of the double-bend nanowires. Geometry-controlled ballistic thermoelectric effect could potentially be explored to design thermoelectric devices such as thermocouples at nanoscale.
