Different contributions to the self-consistent heavy-hole potential for the same system of Figure1. With (a) N A = 1 × 1018 cm−3, (b) N A = 2 × 1018 cm−3, (c) N A = 4 × 1018 cm−3, and (d) N A = 6 × 1018 cm−3. Dotted line indicates the Coulomb potential, V C ; dashed line indicates the exchange-correlation potential, V XC , and solid line indicates the total potential give by the sum of V C and V XC .
