Nanowerk September 14, 2021 Using molecular beam techniques researchers in Germany succeeded in depositing a single layer of indium atoms as triangular lattice on a silicon carbide crystal as support resulting in indenene. The relevant electrons occupy free space in between the indium positions. Their charge fills the “negative” of the triangular indium lattice which is actually a honeycomb lattice. Unlike graphene, indenene needs not to be cooled down to ultra-low temperatures to manifest its properties as a topological insulator. The simple structure of indenene represents at the same time a challenge: as soon as the single layer of indium […]
