Methods and devices for controlling thermal conductivity and thermoelectric power of semiconductor nanowires are described. The thermal conductivity and the thermoelectric power are controlled substantially independently of the electrical conductivity of the nanowires by controlling dimensions and doping, respectively, of the nanowires. A thermoelectric device comprising p-doped and n-doped semiconductor nanowire thermocouples is also shown, together with a method to fabricate alternately p-doped and n-doped arrays of silicon nanowires.

Methods and devices for controlling thermal conductivity and thermoelectric power of semiconductor nanowires

A patterning method for the creation of two-dimensional nanowire structures. Nanowire patterning methods are used with lithographical patterning approaches to form patterns in a layer of epoxy and resist material. These patterns are then transferred to an underlying thin film to produce a two-dimensional structure with desired characteristics.
