Nanomesh - Boron Nitride Nanomesh as a Scaffold for Nanocatalysts, Nanomagnets and Functional Surfaces

Objective

The NanoMesh project is based on the recent discovery by one of the proposing groups of a spectacular nanostructure of hexagonal boron nitride that self-assembles on a rhodium metal surface [M. Corso et al., Science 303, 217 (2004)]. It is a supported, m esh-like structure consisting of two atomic layers with a periodicity of 3.2 nm and holes of about 2 nm. The relevance of the project to the thematic area 3.4.1.1 is twofold. With roughly 400 boron and nitrogen atoms in the mesh unit cell, the self-assem bly process is truly remarkable, and it is accessible to live observation by surface science techniques, including scanning tunneling microscopy under process conditions. By elucidating the self-assembly mechanism in this highly non-trivial case, the pro ject is very likely to provide new and general insight in this efficient and cheap type of nanostructure formation. The second key point of relevance lies in the nature and the stability of the boron nitride nanomesh. It is inert and stable up to 1000 K, and it thus lends itself perfectly as a template or scaffold material for forming secondary nanostructures. Metal deposition on the nanomesh is expected to produce highly monodisperse metallic nanoclusters that represent prime candidates for catalysts w ith high activity and selectivity, or for nanostructured magnets with superior magnetic or spintronic properties. The edges around the pores of the mesh permit the stable covalent attachment of organic or even biological molecules of desired functionali ty, thus leading to well structured functional surfaces. The attachment of large molecules should lead to higher hierarchies of self-assembling supramolecular structures that should be very interesting for biotechnology applications. In full expectation of these applications, the project also addresses the production issues related to precursor molecules and substrates.
