In 1965, a well-known physicist, Philip W. Anderson, discovered that ferroelectric metals were good conductors of electricity even without existing in nature and theorized it. However, for many years, scientists thought that it would not be possible to prove this theory given by the Princeton University physicist, who shared the Nobel Prize in physics in 1977. Although it was like trying to mix water and fire, but an international team of scientists, led by Rutgers University, recently verified the theory and their outcomes are published in Nature Communications. Jak Chakhalian, the holder of the Professor Claud Lovelace Endowed Chair at the Rutgers University, New Jersey, and a participant in the research, stated that it is exciting for them that they created a new segment of two-dimensional artificial materials that have ferroelectric-like properties at normal room temperature that actually do not exist in nature; however, can conduct electricity. It is a significant link between the theory and the experiment.
“Ferroelectric materials are utilized in various electronic products, such as high precision motors, cell phone, computer storage, medical equipment, sonar equipment, and ultra-sensitive sensors. None of the materials is a conductor of electricity. These findings could potentially spawn a new generation of applications and devices,” said Chakhalian. “Technologically, ferroelectrics are a significant class of materials. They shrink, expand, and move when electricity is applied and that enables one to shift things with precision. Furthermore, every modern mobile phone has tens of components with the properties similar to ferroelectric materials,” he added.
