Abstract
A nanocomposite thermoelectric conversion material includes a matrix and semiconductor nanowires dispersed as a dispersant in the matrix. The semiconductor nanowires are arranged unidirectionally in a long axis direction of the semiconductor nanowires.
Claims8
A nanocomposite thermoelectric conversion material comprising:
- a matrix;
- and
- semiconductor nanowires dispersed in the matrix, wherein the semiconductor nanowires are arranged unidirectionally in a long axis direction of the semiconductor nanowires, and
- the nanowires have a length of at least 50 nm in the long axis direction and a width of at most 20 nm in a cross-section orthogonal to the long axis direction.

A method of manufacturing a nanocomposite thermoelectric conversion material, comprising:
- preparing a fluid that contains salts each of which has a different element making up a thermoelectric conversion material, which the salts being formed into a matrix and a dispersant that have same slip plane;
- producing composite particles of the thermoelectric conversion material by adding, in a dropwise manner, a solution containing a reducing agent to the fluid;
- and
- applying pressure to the composite particles such that the dispersant is formed into nanowires and the nanowires are arranged unidirectionally, wherein the fluid includes a solution or a slurry.
