Symmetry in Electron-Atom Collisions and Photoionization Process
... related. Indeed it is, but the relationship is subtle. The difficulty in relating the two processes comes from the fact that even if the final state of the two processes is the same, the initial states are different: even the ingredients of the initial states are different for the two processes! By ...

... • h+ is simply a missing electron, which leaves an excess positive charge (due to an extra proton) • Recombination – if an e- and an h+ come in contact, they annihilate each other • Electrons and holes are called “carriers” because they are charged particles – when they move, they carry current • Th ...

... particles? Electrons and positrons are fundamental particles, ie they are not made of anything else. When an electron moving in one direction collides with a positron moving with equal speed in the opposite direction, they completely annihilate and twice the beam-energy is available to make new part ...
