WebThe Debye screening length due to chain sections r D (Z) is smaller than the solution correlation length ξ. This means that there is less than one polyion section inside a Debye volume c Z r D 3 ( Z ) < < 1 contradicting the assumption of the Debye–Huckel theory. WebApr 25, 2024 · Debye length is a measure for the electrostatic screening in plasma, colloids or in a semiconductor material. It is very relevant to determine the stability and the use of surfactants for colloidal solutions and also for the depth profiling technique used to measure the doping profile in semiconductor materials. It is ...
