Copper(I) telluride is an inorganic compound with the chemical formula Cu 2 Te. It can be synthesized by reacting elemental copper and tellurium with a molar ratio of 2:1 at 1200 °C in a vacuum. [3] Cu 2 Te has potential applications in thermoelectric elements and in solar cells, where it is alloyed with cadmium telluride to create a ...
Thomas Johann Seebeck (1780–1831) discovered the thermoelectric effect in 1821. The symmetrical Peltier effect (Jean Charles Athanse Peltier, 1785–1845) uses an electric current to produce temperature differences. In the middle part of the twentieth century the thermo-electric generator was often used in place of galvanic batteries. [2]
The typical efficiency of TEGs is around 5–8%, although it can be higher. Older devices used bimetallic junctions and were bulky. More recent devices use highly doped semiconductors made from bismuth telluride (Bi 2 Te 3), lead telluride (PbTe), [10] calcium manganese oxide (Ca 2 Mn 3 O 8), [11] [12] or combinations thereof, [13] depending on application temperature.
Copper ditelluride is an inorganic compound with the chemical formula CuTe 2. It is a superconductor with a C18 structure and a transition temperature of 1.3 K. [ 2 ] CuTe 2 crystals can be synthesized by reacting elemental copper and tellurium with a molar ratio of 1:2 at a pressure of 65 kbar for 1–3 hours at 1000–1200 °C, followed by ...
Conversion of the decay heat of the plutonium to electrical power was accomplished through 312 silicon-germanium (SiGe) thermoelectric couples. A hot junction temperature of 1273 K (1832 °F) with a cold junction temperature of 573 K (572 °F) compose the temperature gradient in the thermoelectric couple in the RTG. [9]
Copper telluride may refer to: Weissite, a mineral, Cu 2−x Te; Rickardite, a mineral, Cu 7 Te 5 (or Cu 3−x (x = 0 to 0.36) Te 2) Copper(I) telluride, Cu 2 Te; Copper(II) telluride, CuTe, which occurs as the mineral vulcanite; Copper ditelluride, CuTe 2; Tellurium copper, copper alloy with tellurium
A thermal copper pillar bump, also known as a "thermal bump", is a thermoelectric device made from thin-film thermoelectric material embedded in flip chip interconnects (in particular copper pillar solder bumps) for use in electronics and optoelectronic packaging, including: flip chip packaging of CPU and GPU integrated circuits (chips), laser diodes, and semiconductor optical amplifiers (SOA).
Copper(II) telluride is an inorganic compound with the chemical formula CuTe that occurs in nature as a rare mineral vulcanite. References This page ...
