Nanostructured thermoelectric laminates and a method to enhance the power factor and aerial power density of such thermoelectric laminates based on vertically oriented and densly arrayed nanowires

摘要

Nanostructured elements and a method for fabricating such nanostructured elements with an enhanced power and aerial power density are disclosed. A hierarchical template with ordered and arrayed nanopores is produced on either a mating part or a support material that is pre-shaped so as to be conformable to the mating part. At least one compound can be optionally layered within the nanopores to reduce the diameter thereof. The template is supplied with filling material having selected electrical or thermoelectric properties. Selective removal of the template produces freestanding nanostructure arrays which are then backfilled with thermoelectric material or the like to form a nanostructure array comprised of nanowires supported by the backfilled material on the substrate.

1. A method for fabricating a nanostructured thermoelectric device with an enhanced power and aerial power density, comprising: producing a hierarchical template with ordered and arrayed nanopores on one of a mating part and a support material that is pre-shaped so as to be conformable to the mating part, optionally layering at least one compound within the nanopores to reduce the diameter thereof, supplying the template with a thermoelectric filling material; and selectively removing the template to produce freestanding nanostructure arrays and then backfilling the nanostructure arrays on the template with a thermoelectric backfilling material to form nanowires supported by the thermoelectric backfilling material.
