The plasmon resonant scattering peak positions and enhancement factor for gap dimensions between 0.1 nm and 10 nm can be calculated using both the local model and the nonlocal model ( Fig. It is an important part of the behavior of charge-carrying fluids, such as ionized gases (classical plasmas), electrolytes, and charge carriers in electronic conductors ( semiconductors, metals). Looking closer yet, it can be seen that the fields penetrate into the nanosphere by a distance on the order of the Thomas-Fermi screening length. In physics, screening is the damping of electric fields caused by the presence of mobile charge carriers.
