1 Introduction Topological insulators are a class of materials characterized by an insulating band gap in their bulk and topologically protected conducting states at their surface or edges.[1, 2] These appealing materials have received a huge amount of attention in the last decades,[3-6] and are currently being considered as the basis of fault-tolerant “topological” quantum computation.[7, 8] Recently, it has been shown that topologically-protected states may be finely engineered in bottom-up...
