Debye Length Formula

Equation for calculate debye length is,

λ_D = √[ε₀•k_B•T_e] / [n_e•q²_e]

where
ε₀ = permittivity of free space, (ε₀ = 8.854187817 × 10⁻¹² F.m⁻¹)
k_B = the Boltzmann constant, (1.38064852×10⁻²³ J/K)
T_e = temperatures of the electrons,
n_e = the density of electrons,
q_e = the charge of an electron (1.6021766208×10⁻¹⁹ C),
λ_D = the Debye length
