Electrons that remain undetected within solid materials play a crucial role in unveiling the properties of high-temperature superconductors, potentially shedding light on other enigmas in material science.
The inherent characteristics of materials, such as electrical conductivity and light reflection, are primarily influenced by the behavior of their electrons. Spectroscopy, a technique that involves shining light on materials and analyzing the reflected spectrum, is commonly used to understand which frequencies are absorbed or reflected, providing insights into material properties.
