J. Koski, Judy J. Cha, Bryan W. Reed, Colin D. Wessells, Desheng Kong, Yi CuiA major goal of intercalation chemistry is to intercalate
high
densities of guest species without disrupting the host lattice. Many
intercalant concentrations, however, are limited by the charge of
the guest species. Here we have developed a general solution-based
chemical method for intercalating extraordinarily high densities of
zero-valent copper metal into layered Bi2Se3 nanoribbons. Up to 60 atom % copper (Cu7.5Bi2Se3) can be intercalated with no disruption to the host
lattice using a solution disproportionation redox reaction.
