PREMIER CAT - Determining local composition of the interleaved ferecyrstal system (LaSe1-x)1.16(VSe2-y)n (n=2, 3, 4) using electron miscroscopy techniques.


EMSL Project ID

Abstract

The layered intergrowth system (LaSe1-x)1.16(VSe2-y)n (n=2, 3, 4) was prepared using the modulated elemental reactant (MER) technique. Preliminary electron probe micro-analysis (EPMA) revealed non-stoichiometric ratios of the constituent subunits. In-plane diffraction data as well as cross-sectional HAADF-STEM point to novel structural features. It is believed that local composition information will help to illustrate the relationship between structure and properties.
