Debye Length, which is defined as the shielding length of a charged particle in plasma, is directly proportional to the square-root of the thermal energy of the electrons and inversely proportional to the number density of electrons in plasma. Debye length is defined as the radius of the sphere around a single charged particle that is formed by the crowding of oppositely charged particles. The Debye-Hückel limiting law, named for its developers Peter Debye and Erich Hückel, provides one way to obtain activity coefficients [1].
