Debye length
Measure of electrostatic effect and how far it persists
Debye length
In plasmas and electrolytes, the Debye length λ D {\displaystyle \lambda _{\text{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 electrostatic effect persists. With each Debye length the charges are increasingly electrically screened and the electric potential decreases in magnitude by e. A Debye sphere is a sphere whose radius is the Debye length. Debye length is an important parameter in plasma physics, electrolytes, and colloids (DLVO theory). The Debye length for a plasma consisting of particles with density n {\displaystyle n} , charge q {\displaystyle q} , and temperature T {\displaystyle T} is given by λ...
