Stable 2D conductive and transparent metal/metal(hydr)oxide multilayers prepared by manipulated wetting — •Sebastian Runde, Heiko Ahrens, Harm Wulff, and Christiane A. Helm — Institute of Physics, Universität Greifswald, Felix-Hausdorff-Str. 6, 17489 Greifswald

We present a new deposition method allowing ultrathin, conductive and transparent metal-containing layers to be prepared at ambient conditions with cm² areas on glass substrates. Multilayers are formed by repetition of the deposition procedure, induced break-up after forced wetting. Different liquid metals and their alloys, Bismuth, Gallium, Indium and Tin were used and compared. These metals all have a low melting temperature, a high wettability and form instantaneously a passivating oxide skin. X-ray measurements show that multilayer thickness increases linearly with the number of deposition cycles, yielding a reproducible single layer thickness between 3 and 6 nm. The largest layer number achieved was 13 (54 nm thick). The sheet resistance and the optical absorbance decrease monotonically with the number of deposited layers.
