Self-similarity in the energy spectrum of a InAs/GaSb Fibonacci superlattice. The left panel shows the whole spectrum for an order superlattice, whereas the central and right panels show a detail of the spectrum for superlattices of orders and , respectively (from [47], with permission from IOP Publishing Ltd.).
