WebInterpretation 1 is a physical property of Debye shielding; it involves the distance where a sort of equilibrium is established between the ‘source’ of the shielding that is the restoring electric potential, and the ‘sink’ of the shielding that is the disturbing thermal energy. In contrast, Interpretation 2 is simply a mathematical ... WebThe Debye length, is a measure of the shielding distance or thickness of the sheath. Note that larger density indicates better shielding effects, as one would expect, since each layer of plasma contains more electrons. Furthermore, λ D increases with increasing k B T ∗.
