    Superconductors allow electricity to pass through them with almost zero resistance. In superconductors are carriers of electric current.

    Photons are light particles.

    Holes are charge carriers responsible for current in semiconductors.

    Phonons are quantum of energy or quasiparticles associated with a compressional wave such as sound or a vibration of a crystal lattice.
