(a)-(c) show how the Seebeck coefficient varies for 1D, 2D and 3D materials, while (d)-(f) show the thermoelectric conductivity for the same systems. No major changes in the shape of the curves are seen for (a)-(c); drastic changes are seen for (d)-(e) beyond a threshold range marked in yellow, making thermoelectric conductivity a much more sensitive, unambiguous measure for dimensionality.

Abstract:
Researchers from Tokyo Metropolitan University have shown that a quantity known as thermoelectric conductivity is an effective measure for the dimensionality of newly developed thermoelectric nanomaterials. Studying films of semiconducting single-walled carbon nanotubes and atomically thin sheets of molybdenum sulfide an
