Superconductivity in the lab
We have learned a fair bit of background information on superconductivity.
In this video Dr. Yi Du takes us into the lab and shows us the work that is currently been undertaken in regards to superconductivity. Superconductivity “is a phenomenon in which the resistance to the material of the electric current is zero”.
Some of the key terms used in this section are:
STM – Scanning Tunnelling microscope. This microscope works by measuring tiny tunnelling electrical currents between a sharp tip and a material surface. The arrangement and electronic features can be mapped with atomic resolution.
Cooper Pairs – a loosely bound pair of electrons and is more stable than a single electron within the lattice. They experience less resistance and can carry the supercurrent.
