Artificially layered superconductor materials based on crystalline multilayer structure are of potential interest due to the unusual quantum effects which could be expected in materials of this type. Scanning tunneling microscopy has recently been used (e.g. see Figure) to measure the modulation wavelength (the bilayer thickness) and to estimate the composition profile in such superlattices.
