Pyridine intercalated Bi${}_2$Se${}_3$ heterostructures: controlling the topologically protected states

I. S. S. de Oliveira, R. H. Miwa

We use ab initio simulations to investigate the incorporation of pyridine molecules (C${}_5$H${}_5$N) in the van der Waals gaps of Bi${}_2$Se${}_3$. The intercalated pyridine molecules inc…
