Scientists from the University of New South Wales (Australia) managed to make a discovery, through which the development of the computer industry can get a new impetus. In the course of the research, they synthesized a metal whose existence had previously been predicted only theoretically.
Studying the compounds of the refractory metal tungsten (W) with brittle tellurium (Te), the researchers obtained an alloy (WTe2), which can be attributed to ferroelectrics. It has both dielectric and metal properties at the same time. The theoretical existence of such substances was described in the 60s, but it was possible to obtain it only now.
The main problem faced by scientists in the past was the inability to detect ferroelectric properties due to the rapid oxidation of thin films of tungsten and tellurium compounds in the air. This process destroyed the crystal structure of the alloy. The peculiarity of ferroelectric and ferroelectric metals is the uneven arrangement of electrons. Their position can be controlled by strong electric fields, that is, such a metal is amenable to "programming".
Such ferroelectrics are planned to be used as a "memory of the future". In theory, the speed of these drives will be comparable to RAM. In addition, they will be able to save data even after the power is turned off. In addition, writing and reading information will consume a minimum of energy.
