Tuning the Topological Band Gap of Bismuthene with Silicon-based Substrate
Nils Wittemeier, Pablo Ordejón, Zeila Zanolli
Some meta-stable polymorphs of bismuth monolayer (bismuthene) can host topologically nontrivial phases. However, it remains unclear if these polymorphs can become stable through in…

Interference effects in one-dimensional moiré crystals
Nils Wittemeier, Matthieu J. Verstraete, Pablo Ordejón +1
Interference effects in finite sections of one-dimensional moiré crystals are investigated using a Landauer-Büttiker formalism within the tight-binding approximation. We explain in…
