The departure of electronic distribution from local electrical neutrality and the additional energy due to such a departure in compositionally modulated structures are calculated using a simplified Thomas-Fermi equation. With this energy, we have derived the variation of the biaxial modulus with the modulation period. The result agrees at least qualitatively with experimental findings of supermodulus effect in such structures.
