CONCEPT OF ENERGY GAP IN SUPERCONDUCTORS

ABSTRACT

The concept of Superconductors in relation to energy gap was considered in this study. The occurrence of the Meissner effect indicates that superconductivity cannot be understood simply as the idealization of perfect conductivity in classical physics. The major aim of this project is to study the concept of energy gap in super conductors other objectives of this study are to appraise the rate of superconductivity for energy gaps and to appraise the effectiveness of energy gap in superconductors. Superconductivity can be seen as a complete disappearance of electrical resistance in various solids when they are cooled below a characteristic temperatureThe use of superconductors in magnets is limited by the fact that strong magnetic fields above a certain critical value cause a superconductor to revert to its normal, or non superconducting state. The theory of superconductivity has been tested in a wide range of experiments, involving, for example, ultrasonic absorption studies, nuclear-spin phenomena, low-frequency infrared absorption, and electron-tunneling experiments. In conclusion, superconductor energy gaps arise from changes in system entropy between the superconductor and the normal conductor in the phase transition and the ratio of the superconductor energy gap to the superconductor critical temperature depends upon the chemical structure of superconductor.
