Quantum Nanostructures: Energy Levels and Superlattices

This lecture delves into the calculation of quantized energy levels in quantum wells, exploring the specificity of hole states and true quantum wells with varied confinement potentials. The transfer matrix method is introduced, followed by the physics of superlattices, where identical quantum wells interact to form minibands. The impact of dimensionality on excitonic properties is discussed, highlighting the enhanced stability of excitons compared to the bulk case.
