TaS2 can be synthesised in the 4Hb stacking, a natural heterostructure of “H" and “T"-type layers, which exhibits several unusual phenomena in its low temperature superconducting phase. Here, its layer-dependent electronic properties are explored, revealing the T layers are effectively insulating in the bulk, though not at the surface.
