Electrons that may’t be detected inside supplies nonetheless play a job in figuring out their properties
Dmytro Razinkov/Alamy
“Dark” electrons inside stable supplies might assist us study extra in regards to the behaviour of high-temperature superconductors, and maybe clear up different mysteries in materials science.
Most of a fabric’s properties, similar to how simply it conducts electrical energy or displays mild, are dictated by the movement of its electrons. A method 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 a view to reveal which frequencies are absorbed or mirrored.
