Scientists from the University of New South Wales (Australia) managed to make a discovery, thanks to which the development of the computer industry can receive a new impetus. In the course of research, they synthesized a metal, the existence of which had previously been predicted only theoretically.
Studying the compounds of the most refractory metal tungsten (W) with brittle tellurium (Te), the researchers obtained an alloy (WTe2), which can be attributed to ferroelectrics. It simultaneously possesses both dielectric and metal properties. The theoretical existence of such substances was described as far back as the 1960s, but it was only now possible to obtain it.
The main problem faced by scientists in the past was the impossibility of detecting the 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 lies in the uneven arrangement of electrons. Their position can be controlled by strong electric fields, that is, such a metal can be "programmed".
Such ferroelectrics and plan to use as a "memory of the future." In theory, the speed of these drives will be comparable to RAM. In addition, they can save data even after a power outage. In addition, the recording and reading of information will consume a minimum of energy.
