Hybrid metal/semiconductor superlattices are obtained by the controlled compression of rolled-up metal/semiconductor nanomembranes. The planar superlattice maintains the crystalline quality of the semiconductor and the polycrystalline texture of the metal, allowing the integration of these materials into a multilayer system that cannot be produced by any direct deposition procedure. The superlattice consists of two symmetrically inverted multilayer stacks splitted by a metallic mirror plane. Additional intensity peaks in x-ray reflectivity confirm the periodic structure created by the roll up and compression of nanomembranes.

    A recent claim [Eur. Phys. J. Appl. Phys. 40, 293 (2007)] demonstrating a nuclear process triggered by electrolysis is challenged. An analysis, based on relative diameters, is used to demonstrate that predominant pits could not possibly be attributed to alpha particles, or to less massive...

    Earlier we reported, in this journal, that the pits generated in CR-39 detectors during Pd/D co-deposition experiments are consistent with those observed for pits that are of a nuclear origin. Recently, that interpretation has been challenged. In this communication, additional experimental data...
