摘要： A thermoelectric module comprised of a quantum well thermoelectric material with low thermal conductivity and low electrical resitivity (high conductivity) for producing n-legs and p-legs for thermoelectric modules. These qualities are achieved by fabricating crystalline quantum well super-lattice layers on a substrate material having very low thermal conductivity. Prior to depositing the super-lattice thermoelectric layers the low thermal conductivity substrate is coated with a thin layer of crystalline semi-conductor material, preferably silicon. This greatly improves the thermoelectric quality of the super-lattice quantum well layers. In preferred embodiments the super-lattice layers are about 4 nm to 20 nm thick. In preferred embodiments about 100 to 1000 of these super-lattice layers are deposited on each substrate layer, to provide films of super-lattice layers with thicknesses of in the range of about 0.4 microns to about 20 microns on much thicker substrates. The substrates may be a few microns to a few millimeters thick. The thermoelectric films are then stacked and fabricated into thermoelectric p-legs and n-legs which in turn are fabricated into thermoelectric modules. These layers of quantum well material may in preferred embodiments be separated by much thicker layers of thermal and electrical insulating material such that the volume of insulating material in each leg is at least 20 times larger than the volume of quantum well material.

摘要： Quantum well thermoelectric modules and a low-cost method of mass producing the modules. The devices are comprised of n-legs and p-legs, each leg being comprised of layers of quantum well material in the form of very thin alternating layers. In the n-legs the alternating layers are layers of n-type semiconductor material and electrical insulating material. In the p-legs the alternating layers are layers of p-type semiconductor material and electrical insulating material. Both n-legs and p-legs are comprised of materials providing similar thermal expansion. In preferred embodiments the layers, referred to as super-lattice layers are about 4 nm to 20 nm thick. The layers of quantum well material is separated by much larger layers of thermal and electrical insulating material such that the volume of insulating material in each leg is at least 20 times larger than the volume of quantum well material.

摘要： A thermoelectric module having a gapless insulating eggcrate providing insulated spaces for a large number of p-type and n-type thermoelectric elements. The absence of gaps in the walls of the spaces virtually eliminates the possibility of interwall shorts between the elements. Electrical connections on both the hot and cold sides of the module electrically connect the elements in series or in parallel as desired. Usually, most or all of the elements will be connected in series. In a preferred embodiment, the gapless eggcrate is formed from a high temperature plastic. In a preferred embodiment, two lead wires are added before adding the hot and cold side electrical connections. In this embodiment, electrical connections on the hot and cold sides comprise a thin layer of molybdenum and a coating of aluminum over the molybdenum. The surfaces are ground down to expose the insulating eggcrate walls except where connections between the elements are desired. In this preferred embodiment a seal is then applied over both the hot and cold surfaces. The seal preferably is comprised of a very thin electrically insulating layer and over this electrically insulating layer a thin metal layer is provided.
