Understanding the Basics of Superconductivity
Superconductivity is a phenomenon where a material can conduct electricity without resistance, arising under specific conditions, notably at very low temperatures. This property suggests that energy can be transmitted without loss, making superconductors vital for various advanced technologies. The roots of superconductivity date back to the discovery of solid mercury by Heike Kamerlingh Onnes, who first observed this remarkable behavior over a century ago. Since then, researchers have dedicated themselves to understanding how materials achieve this state and how it can be harnessed for practical applications.
Fundamentally, superconductivity involves the pairing of electrons into Cooper pairs, which move through the lattice of the superconductor without scattering, thus avoiding energy loss. The ideal conditions for superconductivity include achieving extremely low temperatures, which affect the lattice vibrations or phonons that can disrupt these pairs. Researchers have focused on various materials, from conventional superconductors like aluminum to more exotic compounds, with the goal of finding materials that exhibit superconductivity at higher temperatures.
