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