Abstract:
Diamond-like carbon based thermoelectric conversion devices and methods of making and using the same which have improved conversion efficiencies and increased reliability. The device can include a cathode (25) having a base member (60) with a layer of diamond-like carbon material (5) such as amorphous diamond coated over the cathode (25). A dielectric intermediate member (55) can be electrically coupled between the diamond-like carbon material (5) and an anode (30). Various additional layers and configurations can allow for improved performance such as multiple cathode layers and/or multiple intermediate layers. The thermoelectric conversion devices can be configured as an electrical generator and/or a cooling device and can be conveniently formed. In addition, the devices of the present invention do not require formation of a vacuum space and are typically completely solid throughout. As a result, the devices of the present invention are susceptible of mass production at reduced costs and have improved conversion efficiencies and reliability.
Abstract:
Diode devices are disclosed in which the separation of the electrodes (1, 5) is set and controlled using piezo-electric, electrostrictive, or magnetostrictive actuators (20). This avoids problems associated with electrode spacing changing or distorting as a result of heat stress. In addition it allows the operation of these devices at electrode separations which permit quantum electron tunneling between them. Pairs of electrodes whose surfaces replicate each other are also disclosed. These may be used in constructing devices with very close electrode spacings.
Abstract:
A heterostructure thermionic cooler and a method for making thermionic coolers, employing a barrier layer of varying conduction bandedge for n-type material, or varying valence bandedge for p-type material, that is placed between two layers of material. The barrier layer bandedge is at least kBT higher than the Fermi level of the semiconductor layer, which allows only selected, 'hot' electrons, or electrons of high enough energy, across the barrier. The barrier layer is constructed to have an internal electric field such that the electrons that make it over the initial barrier are assisted in travel to the anode. Once electrons drop to the energy level at the anode, they lose energy to the lattice, thus heating the lattice of the anode. The barrier height of the barrier layer is high enough to prevent the electrons from traveling in the reverse direction.
