One-dimensional molecular self-assembly on vicinal surfaces (MOL-VIC)

纳米范围内的分子结构在未来的电子数据存储和处理设备中表现出巨大的应用潜力。当通过在合适的基底上的自组装过程产生时，这样的结构特别令人感兴趣。邻位表面非常适合作为图案化模板，用于在纳米尺度上大规模制造一维结构，其中传统的光刻技术不再可行或负担得起。邻位表面显示出双重对称形态，因此，保留在原子或分子吸附和薄膜生长后的所有物理性质的完全各向异性。此外，可以产生具有1 nm至100 nm尺度的周期性的台阶、刻面和原子行的一维图案。我们将利用这个独特的机会，准备模板的平行分子组装的周期性结构。联合收割机结合了参与小组在纳米结构模板制备、分子合成和表面组装、原位分子操纵和光谱学、电子结构表征和理论计算方面的专业知识，为定制分子组装体的生产提供科学依据。

Molecular structures in the nanometer range exhibit an enormous potential for applications in future electronic data storage and processing devices. Such structures are particularly interesting when created through the process of self-assembly on suitable substrates. Vicinal surfaces are ideally suited as patterned templates for the mass fabrication of one-dimensional structures on the nanometer scale, where conventional lithographic techniques are no longer feasible or affordable. Vicinal surfaces display a two-fold symmetric morphology and, consequently, a complete anisotropy of all physical properties that is retained upon atom or molecule adsorption and thin-film growth. Furthermore, one-dimensional patterns of steps, facets and atomic rows with periodicities on a scale of 1 nm to 100 nm can be produced. We will utilize this unique opportunity to prepare templates for parallel molecular assembly of periodic structures. We combine the expertise of participating groups in nanostructured template preparation, molecule synthesis and assembly on surfaces, in-situ molecule manipulation and spectroscopy, electronic structure characterization, and theoretical calculations to provide the scientific basis for the production of customized molecular assemblies.
