Intercalates of BiSe studied by time-resolved powder X-ray diffraction and neutron diffraction

Intercalation of lithium and ammonia into the layered semiconductor Bi 2 Se 3 proceeds via a hyperextended (by >60%) ammonia-rich intercalate, to eventually produce a layered compound with lithium amide intercalated between the bismuth selenide layers which offers scope for further chemical manip...

Description
Summary:Intercalation of lithium and ammonia into the layered semiconductor Bi 2 Se 3 proceeds via a hyperextended (by >60%) ammonia-rich intercalate, to eventually produce a layered compound with lithium amide intercalated between the bismuth selenide layers which offers scope for further chemical manipulation. New lithium amide/ammonia intercalates of Bi 2 Se 3 are revealed using in situ X-ray powder diffraction.
