Emergence of a correlated insulating state in bulk 1T-NbSe${}_2$ via metal intercalation

M. Tomlinson, AKM A. Rahman, S. Devi +6

The 1T polymorph of NbSe${}_2$, long confined to the monolayer limit, has remained inaccessible in bulk. Here, we report the realization of bulk 1T-NbSe${}_2$ via electrochemical Sn in…
