FM.TES - Tunnel Effect in Superconductors

Please ask tutor about availability

The concept of energy gaps is mainly used in association with insulators, i.e. bad electrical conductors. Surprisingly, many superconductors have an energy gap, too. Why it exists and how it can be measured will be the matter of this experiment. In this lab you will gain insight into designing an experiment to validate a theory, preparation of thin films (Au-Al-Al2O3-Pb-Au) by sputtering and thermal evaporation, creating cryogenic temperatures with liquid 4He down to 2 K and precise measurement of small resistances.
