We present a self-consistent analysis of the Curie temperature (Tc) modulation in Mn δ-doped GaAs/Be-doped AlGaAs heterostructures. Considering the influences of both Mn dopants and Hartree potential, we solve simultaneously the Schrödinger and Poisson equations for different Mn δ-doping positions (ds) and uncompensated Mn atom concentration (NMn). Under low dopant concentration (NMn<4×1015/m2),...
