摘要： A thermoelectric conversion element includes: a thermoelectric member that is columnar; an insulator formed around the thermoelectric member; and a metal layer formed continuously on an edge surface of the thermoelectric member and an edge surface of the insulator. An edge portion of the thermoelectric member and an edge portion of the insulator define a gap covered with the metal layer. The inner portion of the gap covered with the metal layer is a void.

摘要： Exemplary thermoelectric devices and methods are disclosed herein. Thermoelectric generator performance is increased by the shaping isothermal fields within the bulk of a thermoelectric pellet, resulting in an increase in power output of a thermoelectric generator module. In one embodiment, a thermoelectric device includes a pellet comprising a semiconductor material, a first metal layer surrounding a first portion of the pellet, and a second metal layer surrounding a second portion of the pellet. The first and second metal layers are configured proximate to one another about a perimeter of the pellet. The pellet is exposed at the perimeter. And the perimeter is configured at a sidewall height about the pellet to provide a non-linear effect on a power output of the thermoelectric device by modifying an isotherm surface curvature within the pellet. The device also includes a metal container thermally and electrically bonded to the pellet.

The nano-scale energy converters include two electrodes separated a predetermined distance. The first electrode is manufactured to have a first work function value. The second electrode is manufactured to have a second work function value different from the first work function value. A cavity is formed between the first and second electrodes, and a nanofluid is disposed in the cavity. The nanofluid includes a plurality of nanoparticles, with the nanoparticles having a third work function value that is greater than the first and second work function values. The relationship of the work function values of the nanoparticles to the work function values of the electrodes optimizes transfer of electrons to the nanoparticles through Brownian motion and electron hopping.
