By "superlattice" are they referring to van der Waals heterostructures?

  No. You call the regular configuration of atoms of a particular material like GaAs a lattice. Now when you start to grow one type of material on top of another in a regular fashion like layers in a sandwich: 10 nm GaAs 5 nm InAs 10 nm GaAs 5 nm InAs You get what is called a super lattice. It is not an atomistic lattice, but a lattice of material type A and B.

    so the difference is that super latices are thicker?

    Got it, so they've figured out how to deal with lattice constant mismatches?

      Yes they did. That's why you will mostly see combinations of binary materials like GaAs, InAs, AlAs to form super lattices.
