(plasma physics)

The near equality in the density of positive and negative charges throughout a volume, which is characteristic of a plasma.

(solid-state physics)

These calculations solve the charge neutrality equation self-consistently for a four-band model (three conduction sub-bands at [GAMMA], L, and X and one equivalent valence band at [GAMMA]) of GaSb.

The method is based on an iterative and self-consistent solution of the charge neutrality equation with full Fermi-Dirac statistics for the carriers at finite temperature and on the use of statistical analyses to give analytic expressions that represent the calculated data sets.
