Synthesis of four new members of the (PbSe)1.16(TiSe2)n (n = 1, 2, 3, and 4) Family of ferecrystals

A new family of turbostratically disordered misfit layered compounds (ferecrystals), (PbSe)_1.16(TiSe₂)_n, is described with n values of 1, 2, 3 and 4. These compounds were synthesized using the modulated elemental reactant method (MER). The high-resolution transmission electron micrographs of these compounds clearly show rotational disorder in the constituent layers of these compounds. θ - 2θ x-ray diffraction scans contain many 00l superlattice diffraction peaks. The c axis lattice parameters determined from this data show a systematic increase as n, the number of TiSe₂ layer, is increased.
