I think LK99 is a 1D — not 2D — material.

  I still don't understand 0D and 1D. Quantum dots, nanoparticles.. are they really 3D but too small to measure?

    1D just means it conducts in one direction. Like it's got tiny wires in it. It's not particularly unusual; anisotropic conductive adhesive is used in your cellphone to glue the screen on. They tape over the electrical pads, then line up the corresponding LCD pads. The tape allows current to flow vertically between the pads, but for adjacent pads it's insulating. Neodymium magnets are another example. They're made up of a little honeycomb, and inside the cells of the comb are very long, needles of neodymium a single atom thick. They create a magnetic field in a single direction.

      But that's an artifact of using two materials in alternation, not an artifact of one material showing 1d conduction.

      2D in materials science means 1 dimension is nano-sized, typically referring to sheets of material that are 1-2 atoms thick. 1D means 2 dimensions are nano-sized. I'm not hip on superconductor science and haven't heard of 1D/2D being used to describe conducting in 1 or 2 directions, do you have any further reading on that?
