The latest research by Japanese researchers found that when metallic platinum is made into an ultra-thin film with a thickness of only 2 nanometers, it can have characteristics similar to semiconductors such as silicon. Researchers believe that this discovery challenges the traditional cognition of semiconductor materials and helps promote the development of related fields. In the traditional sense, metals and semiconductors are strictly distinguished. Metals generally have good electrical conductivity, while semiconductors are between insulators and conductors, and conductivity can be controlled. Transistors made of common semiconductor materials such as silicon are widely used in various electronic devices. The Kyoto University research team found that when heavy metal platinum is made into an ultra-thin film with a thickness of only 2 nanometers on a magnetic insulator called "yttrium iron garnet," it can control resistance through an external voltage like a semiconductor. In addition, the researchers also found that platinum can greatly adjust and control the effect of "spin-orbit coupling". Spin-orbit coupling refers to the interaction between particle spin and orbital motion, which plays a key role in spintronics and other research. Research on semiconductors or other new materials often involves this effect. The research team said that this discovery is inconsistent with traditional solid-state physics and will help the development of electronics and spintronics. The results of this research have been published in the new issue of the British journal Nature Communications.
