Band diagram at equilibrium with the investigated interfaces highlighted by a dashed green line (a); Comparison between the experimental apparent charge profile and the simulated ones with and without interface defects (b); variations in the apparent charge profile extracted from the simulated C–V as a function of the defect densities placed at the interface between the last barrier and QW3 (c), between QW2/QB2 (d), between QW1/QB1 (e) and between the first barrier and QW1 (f).
