title: Electrically conductive hexagonally ordered nanoporous membranes produced by ion-beam induced carbonization of block-copolymer precursors.
abstract: Highly ordered carbonized nanoporous membranes are produced by ion-beam treatment of self-assembled block copolymer precursor films. The membranes are electrically conductive, as verified by scanning tunnelling microscopy (STM) measurements. The carbonization degree is investigated by means of Raman and infrared (IR) spectroscopy, and the morphology of the films via transmission electron microscopy (TEM). Domains of perfect hexagonal order of the pores are visualized via digital interference of a TEM image of a membrane with computer-generated triangular lattices, producing specific moiré fringes. This novel material could be interesting for applications in nano-catalysis, micro-electronics, and as the grid for STM and TEM imaging of free-standing nano-objects.
