Superconductors

The search is on for a room-temperature superconducting material, with new theories needed to explain high-temperature superconductivity

The terms in bold link to topics in the AQA, Edexcel, OCR, WJEC and CCEA A-level specifications, as well as the IB, Pre-U and SQA exam specifications.

A superconductor’s resistivity becomes zero below a critical temperature, expelling any external magnetic fields. Some superconductors can be modelled in terms of electrons in a lattice of positive ions.
