Abstract :
We have targeted the synthesis of a series of (Bi2Te3)X(SnTe)Y misfit layer compounds to study their potential as thermoelectric materials. Misfit layer compounds generally contain interwoven blocks of compounds (typically dichalcogenides) with a rock salt structure; an example is (PbSe)1.10(NbSe2). The lattice mismatch between the alternating layers is expected to decrease lattice thermal conductivity by increasing phonon scattering. Attempted misfit layer compounds of (Bi2Te3)X(SnTe)Y have been prepared with 2\n\n\t\t
