The majority electron density as a function of the Fermi energy is calculated in zinc blende, n-type GaSb for donor densities between [10.sup.16] [cm.sup.-3] and [10.sup.19] [cm.sup.-3]. 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. Our calculations assume parabolic densities of states and thus do not treat the density-of-states modifications due to high concentrations of dopants, many body effects, and non-parabolicity of the bands. Even with these assumptions, the results are important for itnerpreting optical ...
