Phase transitions in two tunnel-coupled HgTe quantum wells: Bilayer graphene analogy and beyond
Abstract HgTe quantum wells possess remarkable physical properties as for instance the quantum spin Hall state and the “single-valley” analog of graphene, depending on their layer thicknesses and barrier composition. However, double HgTe quantum wells yet contain more fascinating and still unrevealed features. Here we report on the study of …
