2S4-xSex (1.75 ≤ x ≤ 2.75) and Its Lithium Intercalation Compounds. — The
51- 020 CdIn
reddish brown title compounds are characterized by XRD, radial distribution function
analysis, TGA, and scanning tunneling microscopy. They possess a layer structure of
the ZnIn2S4—IIIa type. The lattice parameters a and c both increase with an increasing
amount of Se in the samples. The platelike crystals are not perfectly smooth, but small
crystallites are intergrown with the surface. The lithium intercalated compound
Li1.1CdIn2S2Se 2 shows that the crystallite size decreases due to the intercalation while
the fractional change in interlayer spacing and the fraction of planes affected by defects
increases. The process of intercalation does not result in an expansion of the lattice
parameter c. — (SRIVASTAVA*, S. K.; PRAMANIK, M.; PALIT, D.; HAEUSELER,
