The material more studied at present is Bi2Te3 (tellurium and bismuth alloy).

Thermoelectric devices made of inorganic semiconductor materials such as bismuth telluride are already being used today in certain technological applications.

In animals, inhalation of insoluble compounds such as bismuth telluride provokes the usual lung response of an inert dust.

Also provided is a thermoelectric module (10) having bismuth telluride elements (12, 14) coated with a conductive material (16, 18) that does not require a nickel or other diffusion barrier.

Bismuth telluride is currently the best-known candidate material for solid-state TE cooling devices because it possesses the highest TE figure of merit at room temperature.

However, long-term exposure to bismuth telluride “doped” with selenium sulphide can produce in various species a mild reversible granulomatous reaction of the lung.

The module includes small pillars made of bismuth telluride alloys (Bi2Te3), welded to thin copper electrodes sandwiched between two elastomer sheets.

The researchers could control the orientation of spin of the electrons, and the direction and the strength of the electric current in the topological insulator bismuth telluride, Bi2Te3.

It is in particular the case of the bismuth telluride (Bi2Te3) used in the commercial Peltier modules, or of the alloys silicon-germanium (SiGe) used for the power supply of the space probes in thermoelectric generators with radioisotope.
