摘要：

Deviations from ideal ordering in quantum-dot stacks observed in experiment are compared to growth simulations based on a kinetic Monte Carlo model. Anticorrelated vertical alignment with a weak specificity is only found if the first layer is well ordered. Randomly distributed dots in the first layer lead to correlated vertical alignment preferentially for thin spacers and increased temperature, with gradually improving ordering regarding sizes and arrangement.
