Influence of the zirconium diselenide stoichiometry on its behaviour upon lithium intercalation
Zirconium diselenide belongs to the IVB group transition metal dichalcogenides which have lamellar structures and easily intercalate metals and molecules. From optical measurements (Lee et al., 1969) it appears as a semiconductor with a 1.2 eV energy gap. But from the Gleizes and Jeannin work (1970), it is known that zirconium diselenide does not exist as a stoichiometric compound but as ZrSey with 1.85 < y < 1.95.
