From: Trion X+ in vertically coupled type II quantum dots in threading magnetic field

Potential curvesfor the electron confined in vertically coupled lens-shaped QDs. Solid lines represent energy levels of the Trion X+ and dashed lines, Trion X+. With separation, d, between layers and distance, Z h , between the hole and the layer for zero-magnetic field case (γ = 0).
