Energy levels of on-axis donors in vertically stacked quantum dots with different morphologies
The effect of the quantum dots morphology on the binding energy for a neutral donor in two vertically coupled quantum dots is analyzed. The Hamiltonian is made separable by using the adiabatic procedure. For the limit case in which the quantum dots are merged, our results are in good agreement with those results obtained by other authors. We show that binding energy is strongly dependent on the quantum dot size and shape.
