2D materials.

A series of (PbSe)₁(VSe₂)_n with n = 1,2,3 turbostratic disorder heterostructure materials were synthesized through modulated elemental reactants (MER) method. The in-plane and cross-plane Seebeck coefficient, as well as electron transport properties and Hall coefficient, were measured from 80K to 300K. At the charge density wave (CDW) transition, the Seebeck coefficient decrease by approximately two-fold when the material transforms from CDW state to normal state. And the Raman shift spectra dependence on the temperature of the materials were also measured. All those properties were also compared to the 1-T VSe2 2D materials.
