At a glance:λ_D = √(εkT/(n e²)); the electrostatic screening length. Complements plasma-frequency and electron-density.

Formula

λ_D = √(ε·k·T / (n·e²)).

$$\lambda_D = \sqrt{\frac{\varepsilon_0 k_B T}{n e^2}}$$

How to Use

  1. Enter T and density.
  2. The tool returns the Debye length.

Case Studies

T=300, n=1e16

λ_D ≈ 0.041 mm.

FAQ

Longer λ_D?

Means weaker screening — charge felt farther away.
