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 ...

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
The telluride ion is the anion Te 2− and its derivatives. It is analogous to the other chalcogenide anions, the lighter O 2−, S 2−, and Se 2−, and the heavier Po 2−. [1] In principle, Te 2− is formed by the two-e − reduction of tellurium. The redox potential is −1.14 V. [2] Te(s) + 2 e − ↔ Te 2−
Rickardite is a telluride mineral, a copper telluride (Cu 7 Te 5) [2] or Cu 3-x (x = 0 to 0.36) Te 2. [3] It was first described for an occurrence in the Good Hope Mine, Vulcan district, Gunnison County, Colorado, US, [4] and named for mining engineer Thomas Arthur Rickard (1864–1953). [2]
Charge carrier density, also known as carrier concentration, denotes the number of charge carriers per volume. In SI units, it is measured in m −3. As with any density, in principle it can depend on position. However, usually carrier concentration is given as a single number, and represents the average carrier density over the whole material.
In the table below are Seebeck coefficients at room temperature for some common, nonexotic materials, measured relative to platinum. [8] The Seebeck coefficient of platinum itself is approximately −5 μV/K at room temperature, [ 9 ] and so the values listed below should be compensated accordingly.
