摘要

Transfer matrix method has been used to analyze Curie-temperature (T_c) modulation by polarization-induced built-in electric fields in Mn δ-doped GaN/AlGaN quantum wells. Schrödinger equation is employed to calculate the quantum-confined subband energies and the distribution of their corresponding envelope functions. Based on these, we investigate the dependence of T_c on the built-in electric fields in different structures of quantum well. By changing the asymmetry of double quantum wells (DQW), T_c can be raised up to 3 times.
