Debye screening, also known as Debye shielding, refers to a phenomenon in plasmas and electrolytes where the presence of a charged particle results in the distribution of other charges such that the effective electric field produced by the particle is reduced. This concept is crucial in the field of plasma physics. This tutorial will guide you through the calculation of the Debye screening effective potential.

The Debye screening effective potential (V) can be calculated using the point charge (Q), the distance from Q (r), the electron Debye length (λD), and the permittivity of vacuum (ε0) with the following formula:
This formula and the concept of Debye screening are based on the work of Peter Debye, a Dutch physicist and physical chemist. His contributions to the theory of electrolytes and dipole moments are significant in the fields of chemistry and physics.
The concept of Debye screening is crucial in the study and understanding of plasma behavior. It is applied in fusion reactors, space physics, astrophysics, and also in plasma-based devices such as plasma TVs and fluorescent lamps.
Peter Debye is the primary individual associated with this discipline. He made numerous contributions to the field of physical chemistry and physics, which earned him the Nobel Prize in Chemistry in 1936.
The Debye screening effective potential is a fundamental concept in plasma physics, providing insight into the behavior of charged particles in a plasma. By understanding and calculating this potential, one can gain a deeper understanding of the intriguing world of plasmas and their various applications in real-world devices and phenomena.
