A B S T R A C T S FRIDAY, JULY 2 N A N O S E A 2 0 1 0 Room Calendal 9H00-9H30 Bottom-up elaboration of heterogenous ordered ceramic nanopatterns substrates for deposition of magnetic materials. D. Grosso*(1), M. Faustini(1), D. Lantiat(1), C. Laberty(1) ((1) Laboratoire Chimie de la Matiere Condensée de Paris, UMR UPMC-CNRS 7574, Université Pierre et Marie Curie (Paris 6), Collège de France, 11, place Marcelin Berthelot, 75231 Paris).* presenting author, e-mail: david.grosso@upmc.fr Ceramic (e.g. semiconducting TiO2, or insulating ZrO2, Al2O3) nanopatterns on various substrates (e.g. Si, Au, SiO2, Cr) have been prepared through simple fast, cheap, reproducible, and easy to scale up “bottom-up” approach, involving chemical solution deposition, self-assembly via commercial block copolymers, and thermal treatment.[1] The patterns is composed of hexagonally arranged nanoperforations through which the surface of the substrate remains accessible. The typical thickness of the patterns can be controlled between 5 and 20 nm, while a proper selection of chemical and processing conditions allows to perfectly adjust the motif dimension between 10 and 100 nm.[2] They constitute novel highly ordered heterogeneous Inorganic/inorganic Nano Patterned (INP) substrates, which present a unique combination of thermal, mechanical, and chemical stability with the very interesting characteristics of the ordered nano-heterogeneity associated to the accessibility of the substrate surface through the perforations. Figure 1. From left to right: Bare TiO2 perforated Inorganic NanoPattern (INP); Prussian Blue Analogue chemically growth inside the INP‟s perforations;[3] FePt nanoparticles co-electrochemically generated inside the INP‟s perforations;[4] CoPt percolated media deposited by MBE onto the INP;[5] and Ge nanoparticles elaborated by Solid dewetting onto the INP. In the present contribution, we will first describe how this novel generation of substrates is prepared and how one can perfectly control the morphology and the dimensions of the nanoperforation motifs. We will then show how the ordered topography and chemical heterogeneity can be utilised to direct the distribution of deposited materials. Several examples, gathering chemical and physical deposition processes as shown in Figure 1, will be reported as illustration and demonstration. [1] D. Grosso, C. Boissière, B. Smarsly, T.
