WebZnPS3. ZnPS3 is an insulator 2D material. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. To buy ZnPS3 crystals please click here . The ZnPS3 crystals produced at HQ Graphene have a typical lateral size of ~0.8cm, hexagonal shaped and have a transparent appearance. WebDec 14, 2024 · Topological insulators, on the other hand, are characterized by non-local and quantized topological invariants that cannot change continuously. The most experimentally relevant kinds of topological insulators are therefore characterized by an insulating (gapped) bulk and a conducting (gapless) boundary.
