With each Debye length the charges are increasingly electrically screened and the electric potential decreases in magnitude by 1/e. A Debye sphere is a volume whose radius is the Debye length. Debye length is an important parameter in plasma physics, electrolytes, and colloids (DLVO theory). See more In plasmas and electrolytes, the Debye length $${\displaystyle \lambda _{\rm {D}}}$$ (Debye radius or Debye–Hückel screening length), is a measure of a charge carrier's net electrostatic effect in a solution and how far its … See more The Debye length has become increasingly significant in the modeling of solid state devices as improvements in lithographic technologies have enabled smaller geometries. See more • Bjerrum length • Debye–Falkenhagen effect • Plasma oscillation • Shielding effect See more The Debye length arises naturally in the thermodynamic description of large systems of mobile charges. In a system of $${\displaystyle N}$$ different species of charges, the See more For a weakly collisional plasma, Debye shielding can be introduced in a very intuitive way by taking into account the granular character of such a plasma. Let us imagine a sphere about one of its electrons, and compare the number of electrons crossing … See more • Goldston & Rutherford (1997). Introduction to Plasma Physics.
