As with all particles, electrons can act as waves.

However, with doping, these electrons can act as mobile Cooper pairs and are able to superconduct.

Physics has found that an electron sometimes acts more like what we call a particle.

The electrons act as a virtual cathode (negative electric potential).

An electron bound to an atom, or atoms bound together in a molecule, act a bit like a mass attached to a spring.

In a vacuum, free electrons can act as charge carriers.

The electrons act as a barrier between the control gate and the floating gate.

These negatively charged electrons act as a barrier between the control gate and the floating gate.

The free-moving electrons act just as a gas would; moving in every direction throughout the lattice.

Herbert Fröhlich was first to suggest that the electrons might act as pairs coupled by lattice vibrations in the material.
