Alloy of tungsten and tellurium, with metal and ferroelectric properties

Alloy of tungsten and tellurium, with metal and ferroelectric properties.

The resulting alloy of tungsten and tellurium (WTe2), which has both the metal and ferroelectric properties at room temperature.

The resulting alloy of tungsten and tellurium (WTe2), which has both, and metaland ferroelectric properties at room temperature.

Ferroelectricity is the phenomenon of emergence in a certain temperature range spontaneous polarization in the crystal, even in the absence of an external electric field, which can be reoriented its application. In English literature, the ferroelectricity is called ferroelectricity (eng. – ferroelectricity). This phenomenon of electrons within the crystal are unevenly distributed. With the help of a strong electric field position of the electrons inside the ferroelectric can be controlled. Thus, the ferroelectric amenable to “programming”.

The ferroelectric material also includes signatory salt (C4H4KNaO6), titanate barium BaTiO3, the titanate lead-free PbTiO3 and their solid solutions (zirconate-lead titanate), niobate lithium LiNbO3. They are used as cell memory, for modulation and converting laser radiation in the manufacture of compact low-frequency capacitors with high specific capacitance, piezoelectric and pyroelectric transducers.

Alloy of tungsten and tellurium in the future can be used to create a new kind of computer memory. He will be able to retain information even when power is off.
