Electrons that may’t be detected inside supplies nonetheless play a task in figuring out their properties
Dmytro Razinkov/Alamy
“Dark” electrons inside strong supplies might assist us study extra concerning the behaviour of high-temperature superconductors, and maybe remedy different mysteries in materials science.
Most of a fabric’s properties, equivalent to how simply it conducts electrical energy or displays gentle, are dictated by the movement of its electrons. A technique of figuring out these properties is spectroscopy – shining a light-weight on a fabric and analysing the spectrum of the sunshine that bounces again with the intention to reveal which frequencies are absorbed or mirrored.
