debye length
Quick Summary
The Debye length, denoted by h, is a fundamental spatial parameter in plasma physics. It represents the distance an average thermal electron travels in half the period of a plasma oscillation. A plasma is characterized by having many particles within a sphere of radius equal to the Debye length, and the plasma itself must be significantly larger than this length in all dimensions.1
The Debye-Hückel equation, on the other hand, is used in chemistry to describe properties of electrolyte solutions. It accounts for interactions between charged particles (ions) that cause deviations from ideal solution behavior.2
