(Summary description)Normally, when we think of plasma or plasma, we think of ionized air or hot material from the sun. But if you assume that the free-electron model of metal is carefully thought through, the "gas" of free electrons moving in a positive ion scene is also a "plasma". In metals, the collective oscillation of the positive ion lattice can be quantized into phonon explosion, transmission and annihilation. Similarly, in metals, the collective oscillation of the free electron gas can be thought of as an agitation, or quantized as a burst, transfer, and annihilation of a quasi particle. A plasmon is this quasi particle, perhaps a "plasma unit." It's not an elementary element of a exciton. "Exciton" means "collective excitation" or "excitation "; "Plasmon" means "plasmon, "which is the basic unit of plasma, but it's completely absent. Free electrons and metal ions are the basic units of plasma in metals. There are two types of collective electron shaking in a metal: one in which the whole metal's electrons shake synchronously under the action of an external electric field, and the other in which they shake collectively on the surface of the metal. Because of the metal's effective shielding of the applied electric field, the collective sloshiness does not end up in the microscopic metal (and therefore is not easy to be as dense or cloudy as the high-temperature equivalent ionization proposed in the controlled fusion study), but only in the nanoparticles. Another kind of very common, we often call "metallic luster" also has to do with this. The second form of surface sloshing has been called "surface plasmon". In addition, the plasma cleaning is not fixed in one place, but pass, pass all things, because keeping electronic vibration and metal cations, inevitable part is no longer electrically neutral, but "polarization", focused on the local area and quasi particle properties of polarization, the formation of "surface etc from shock yuan" (SPP) so the name of a man. A little paraphrase, it can be called "surface iso-polariton", indicating that this exciton has the characteristic of "polarization". In this way, surface plasmas can also be classified as "plasmas". But this "plasma" is not the "solid, liquid, gas" side by side of the hot plasma that people think. The above is the CRF vacuum plasma cleaning machine manufacturers on the relationship between free electrons and plasma.
