Surface-Confined Molecular Self-Assembly
The design and fabrication of nanometer-sized entities of defined structure on the nanometer scale is a challenge hardly achievable by large-scale top-down procedures. In particular, alternative techniques are needed to structure surfaces at very small length scales. In nanotechnology the process of self-assembly has become a potent method which allows to vanquish these difficulties. Self-assem...
متن کاملSelf-assembly of parallel atomic wires and periodic clusters of silicon on a vicinal Si111 surface.
Silicon self-assembly at step edges in the initial stage of homoepitaxial growth on a vicinal Si(111) surface is studied by scanning tunneling microscopy. The resulting atomic structures change dramatically from a parallel array of 0.7 nm wide wires to one-dimensionally aligned periodic clusters of diameter approximately 2 nm and periodicity 2.7 nm in the very narrow range of growth temperature...
متن کاملNano Wires by Self Assembly
We present a technique to fabricate nano wires on silicon substrates without any lithography. The wires are 50 nm or less in width, but their lengths can be 10s of micro meters. They can be formed by a single or multiple layers of metals. The wires can be designed to form a network which can be partially released from the substrate to form 3D structures. Such structures may serve as actuators o...
متن کاملMolecular self-assembly of functionalized fullerenes on a metal surface.
We present a combined experimental and theoretical study of the self-assembly of C60 molecules functionalized with long alkane chains on the (111) surface of silver. We find that the conformation of the functionalized C60 changes upon adsorption on Ag(111) and that the unit cell size in the self-assembled monolayer is determined by the interactions between the functional groups. We show that C6...
متن کاملGuided self-assembly of molecular dipoles on a substrate surface
Molecules adsorbed on a substrate surface can self-assemble into a monolayer. This article models the process of self-assembly guided by an external object. The molecules are electric dipoles, diffusing on the surface at an elevated temperature. Pre-pattern a flat mask with a submonolayer of immobile atoms, which gives rise to a patterned contact potential field. Bring the mask to a small dista...
