This model typically applies when charge carriers have been emitted from some region of a solid—the cloud of emitted carriers can form a space charge region if they are sufficiently spread out, or the charged atoms or molecules left behind in the solid can form a space charge region. Space charge effects are most pronounced in dielectric ...
In semiconductor physics, the depletion region, also called depletion layer, depletion zone, junction region, space charge region, or space charge layer, is an insulating region within a conductive, doped semiconductor material where the mobile charge carriers have diffused away, or been forced away by an electric field. The only elements left ...
The mathematical theory of Landau damping is somewhat involved (see § Mathematical treatment).However, in the case of waves with finite amplitude, there is a simple physical interpretation [2]: §7.5 which, though not strictly correct, helps to visualize this phenomenon.
Viewed from a large distance, this screening hole has the effect of an overlaid positive charge which cancels the electric field produced by the electron. Only at short distances, inside the hole region, can the electron's field be detected. For a plasma, this effect can be made explicit by an -body calculation.
John Richardson (born June 10, 1946 in England) is a British special effects supervisor.He is best known for his work on the James Bond film series (Casino Royale, Moonraker, Octopussy, A View to a Kill, The Living Daylights, Licence to Kill, Tomorrow Never Dies, The World Is Not Enough and Die Another Day), all the Harry Potter film series (2001-2011), A Bridge Too Far (1977) and Aliens (1986).
The thickness of such a layer is several Debye lengths thick, a value whose size depends on various characteristics of plasma (e.g. temperature, density, etc.). A Debye sheath arises in a plasma because the electrons usually have a temperature on the order of magnitude or greater than that of the ions and are much lighter.
In condensed matter physics, the Su–Schrieffer–Heeger (SSH) model or SSH chain is a one-dimensional lattice model that presents topological features. [1] It was devised by Wu-Pei Su, John Robert Schrieffer, and Alan J. Heeger in 1979, to describe the increase of electrical conductivity of polyacetylene polymer chain when doped, based on the existence of solitonic defects.
