Here, I’ll keep a list of some of the more technical words that I can’t avoid using from time-to-time. So, in alphabetical order:
Band structure: A map of the allowed quantum states in a crystal material.
Boson: Particles which have an integer value of quantum spin. Many bosons can occupy the same quantum state.
Electron: The “particle” which carries negative charge. In atoms, they buzz around the nucleus, forming something like a cloud of charge. In molecules, they form the bonds that stick atoms together. In solids, they can come free from the atoms and conduct electricity.
Fermion: A particle like an electron or a proton which has half-integer quantum spin. Only one fermion can occupy each quantum state.
Fermi energy: (Or Fermi level) The energy of the last filled state in the band structure of a material.
Micron (or micrometer): A length of one millionth of a meter.
Nanometer: A length of one billionth of a meter.
Neutron: The neutral particle in the nucleus of an atom.
Photon: A quantum of light. Depending on the energy (or wave length), this can be radio waves, infra-red, visible light, UV, or X-rays.
Proton: The positively charged particle in the nucleus of an atom.
Superconductor: A material which conducts electricity with no resistance and without losing any energy.
