- Abstract
The interaction between a rock salt compound, PbSe, and the surface of a dichalcogenide (VSe2) is probed by making PbSe, VSe2, [(PbSe)1.11]1(VSe2)1 and PbSe on VSe2 films. PbSe precursors deposited on SiO2 form rough films with randomly oriented PbSe crystallites. VSe2 precursors deposited on a SiO2 surface form crystallographically aligned films. The precursor to the metastable misfit layer compound [(PbSe)1.11]1(VSe2)1 deposited on SiO2 forms a crystallographically aligned film. PbSe precursors deposited on VSe2 are very crystallographically aligned relative to PbSe deposited on SiO2. This reflects the strong interaction between PbSe and VSe2 at the interface. The results suggest that comparing the degree of crystallographic alignment of films of precursors of prospective constituents on SiO2 relative to depositing them on each other may be a simple test to show if a misfit layer compound will form between the two constituents.
