摘要：

We have integrated one-dimensional organic structures into semiconductor/insulator nanostructures by controlled self-assembly. Stepped Si(111) surfaces with self-organized CaF1/CaF2 stripe patterns serve as mask for selective adsorption of 3,10-di(propyl)perylene. These molecules adsorb preferentially on CaF1 nanostripes, rather than on CaF2, This property is used to fabricate large assemblies of parallel, equidistant stripes 1-15 nm wide. We discuss the selectivity in terms of a mechanism where the HOMO and LUMO of the molecule interact with the valence band and conduction band of CaF1 and CaF2. (C) 1999 Elsevier Science B,V.
