What is the Band Gap Energy in Conventional Superconductors?

The band gap energy is a fundamental property of materials that describes the energy difference between the top of the valence band and the bottom of the conduction band. In conventional superconductors, this energy plays a crucial role in determining the material's electronic and thermal properties. When the temperature is lowered, the band gap energy typically decreases, facilitating the pairing of electrons into Cooper pairs, which are essential for the superconducting state.

How Does Temperature Affect Band Gap Energy?

Temperature has a profound impact on the band gap energy of superconductors. As the temperature increases, thermal vibrations can disrupt the electron pairing process, leading to a reduction in superconductivity. The temperature dependant band gap energy graph illustrates this relationship, showcasing the nonlinear behavior of band gap energy as the temperature varies.
