- Tc – critical temperature of a superconductor
- Specific to each superconductor discovered so far
- Negatively charged electrons – repel each other – lose energy
- Below Tc, they form pairs
- Phonons – atomic vibrations that held these pairs together
- Phonons – a unit of vibrational energy
- Genesis – from oscillating atoms in a crystal
- Negatively charged electrons when pair up – no collisions
- They no longer lose energy when they move
- Practically zero flow to electric current
