Optical studies of lithium intercalated indium selenide
Optical properties of LixInSe are presented as a function of the lithium concentration and temperature. Investigations of the photoluminescence and absorption measurements show that the presence of alternating sheets of lithium ions induces changes in the electronic band structure. New radiative recombination centres due to the lithium insertion are also observed. The Raman spectrum does not change appreciatively, unless it is modified by the presence of excitons near certain resonance conditions.
