McGill University scientists have made an unexpected discovery that can lead to the creation of more stable and ecological electronic devices.
They found that the subtle bismuth shows an abnormal electrical effect that remains unchanged over a wide range of temperatures – from almost absolute zero to room temperature.
This discovery casts doubt on the existing ideas about the physics of materials. Bismuth, which is traditionally considered diamagnetic and does not have special magnetic properties, demonstrated the temperature and non-abnormal effect of Hall (Ahe). This effect creates a voltage perpendicular to the current direction, and previously observed only in magnetic materials. In this case, its existence was unexpected and incomprehensible from the point of view of modern theories.
To study this phenomenon, a team of scientists developed an innovative method of creating ultra -thin bismuth. Using mechanical cutting with microscopically treated plates, they received 68-nanometer layers of material and exposed them to extremely strong magnetic fields. These experiments were conducted in the National Laboratory of Strong Magnetic Fields in Florida.
The leader of the study, Professor Guyom Zerve, confessed that he was convinced of the disappearance of the effect as the temperature rises, but the results were unexpected. Bismuth showed stable behavior even at room temperature, which makes it a promising material for green electronics and other high -tech applications, including space equipment and medical devices.
Scientists are hypothesis that the atomic structure of bismuth can limit the movement of electrons in such a way that it imitates the properties of topological materials. These substances have unique characteristics that can change the principles of computer technology and electronics. The next step of the research group is to study the possibility of converting AHE effect into its quantum counterpart, quantum abnormal effect of Hall (QAHE), which can be a breakthrough in the development of new electronic devices that operate at higher temperatures.
