    Abstract: Methods and apparatus for improved thermal isolation for thermoelectric devices are disclosed. In one embodiment, a thermoelectric device includes a first substrate having a first conductive pad, a second substrate having a second conductive pad, and a gap formed between the first and second conductive pads. At least one of the first and second substrates includes at least one opening positioned adjacent to an outer peripheral edge of the conductive pad. The opening may comprise a trench disposed partially or entirely around the outer peripheral edge of the conductive pad. In operation, the opening inhibits heat transfer between the first and second substrates.

    Abstract: The present invention embodies a solid state thermionic energy converter and is directed to a method and apparatus (10, 104, 108) for conversion of thermal energy to electrical energy, and electrical energy to refrigeration. The present invention maintains a thermal separation between an emitter (12) and a collector (16) through a fractional surface contact (13, 42, 44) of decreasing cross-sectional area towards the point of contact. The fractional surface contacts (13, 42, 44) may be associated with the emitter (12), a barrier (14), or the collector (16). Maintaining a thermal separation between the emitter (12) and the collector (16) provides for ballistic electron transport through the barrier (14) and reduces the transport of electrons through thermal conductivity. Hence, the efficiency is increased through the collection of ballistic electrons and the reduction of thermal conductivity electrons which cannot be collected. The inventive principle works for hole conductivity, as well as for electrons.

    CPC classification number: H01J1/30

    Abstract: A method for promoting the passage of elementary particles at or through a potential barrier comprising providing a potential barrier having a geometrical shape for causing de Broglie interference between said elementary particles is disclosed. In another embodiment, the invention provides an elementary particle-emitting surface (17) having a series of indents. The depth (a) of the indents is chosen so that the probability wave (13) of the elementary particle reflected from the bottom of the indent interferes destructively with the probability wave of the elementary particle reflected from the surface. This results in the increase of tunneling through the potential barrier. When the elementary particle is an electron, then electrons tunnel through the potential barrier, thereby leading to a reduction in the effective work function of the surface.

    Abstract: An improved thermionic electric converter (200) uses a wire grid cathode (220) to provide a larger surface area for electrons to boil off. Alternately or additionally, the larger electron emission surface area can be achieved by using a curved electron emission surface. A laser (242) provides quantum inteference to electrons just before they reach the anode, thereby lowering their energy levels such that they more readily are captured by the anode (206). The arrangement provides improved conversion efficiency and reduced electron scatter.
