摘要： A thermoelectric cooler including a thermoelectric junction and a radiation source. The thermoelectric cooler includes n-type material, p-type material, and an electrical power source. The radiation source emits ionizing radiation that increases electrical conductivity of the n and p type materials. Also detailed is a method of using radiation to reach high coefficient of performance (COP) values with a thermoelectric cooler that includes providing a thermoelectric cooler and a radiation source, with the thermoelectric cooler including an n-type material, p-type material, an electrical power source, and emitting ionizing radiation with the radiation source to increase the electrical conductivity which strips electrons from the n-type material, the p-type material, or both the n-type material and p-type material from their nuclei with the electrons then free to move within the material.

摘要： A thermoelectric material may be composed of an isostructural pair of Heusler compounds, either a pair of full Heusler (FH) X2YZ compounds or a pair of half Heusler (HH) XYZ compounds. In the FH pair, a first compound of the pair may the formula (X1)2Y1Z1, wherein X1 is selected from Fe and Co; Y1 is selected from Ti, V, Nb, Hf, and Ta; and Z1 is selected from Al, Ga, Si, and Sn and a second compound of the pair has the formula (X2)2Y2Z2, wherein X2 is selected from Mn, Fe, Co, Ru, and Rh; Y2 is selected from Ti, V, Mn, Zr, Nb, Hf, and Ta; and Z2 is selected from Be, Al, Ga, Si, Ge and Sn. The first and second compounds of the pair may share two elements in common and have third elements which are different and are either isovalent or have a valency which differs by ±1. In the HH pair, a first compound of the pair may have the formula X1Y1Z1 wherein X1 is selected from Ni and Fe; Y1 is selected from Ti, V, and Nb; and Z1 is selected from Sn and Sb and a second compound of the pair has the formula X2Y2Z2 wherein X2 is selected from Fe, Ru and Pt; Y2 is selected from Ti, V, and Nb; and Z2 is selected from Sn and Sb. The first and second compounds of the pair may share two elements in common and have third elements which are different and are either isovalent or have a valency which differs by ±1. The thermoelectric material at room temperature may have a nanostructured two-phase form having a matrix phase composed of the first compound of the FH pair or the first compound of the HH pair and a nanostructured phase composed of the second compound of the FH pair or the second compound of the HH pair, respectively.

摘要： Embodiments relate to methods of manufacturing and operating nano-scale energy converters and electric power generators. 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.

摘要： A thermoelectric conversion material includes: a base material that is a semiconductor composed of a base material element; a first additional element that is an element different from the base material element, has a vacant orbital in a d orbital or f orbital located internal to an outermost shell of the first additional element and forms a first additional level in a forbidden band of the base material; and a second additional element that is an element different from both of the base material element and the first additional element and forms a second additional level in the forbidden band of the base material. A difference is 1 between the number of electrons in an outermost shell of the second additional element and the number of electrons in at least one outermost shell of the base material element.
