Fabrication of Single-Crystalline Silicon Nanowires by Scratching a Silicon Surface with Catalytic Metal Particles
The successful synthesis of carbon nanotubes has stimulated much research in nanomaterials, in particular, in semiconducting nanostructures, which are interesting for their novel sizeand dimensionality-dependent physical properties, and their potential applications in nanoscale optoelectronics. Silicon is the most important semiconducting material, with its contemporary microelectronic technolo...
متن کاملAzidation of silicon(111) surfaces.
A two-step chlorination/azidation process was reported to prepare azide-modified silicon(111) surfaces. XPS and IR analyses show the covalent bonding of azide with silicon. In combination with scanning tunneling microscopy and spectroscopy analyses, different kinetic rates, azide coverages, and surface-area distributions were derived depending on the azidation solvent.
متن کاملThe mechanism of photohydrosilylation on silicon and porous silicon surfaces.
Visible or UV light activates H-terminated Si surfaces because of the presence of a photogenerated hole in a Si-Si back-bond. Enhancing the lifetime of this hole at the surface increases reactivity. On the basis of photodynamics and electron transfer theory, the prevalence of two mechanisms of photoactivation (internal photoemission versus interband photoexcitation followed by electron transfer...
متن کاملMolecular Monolayers on Silicon Surfaces
Controlled formation of organic molecular monolayers on silicon surfaces offers the promise of enhancing the functionality of existing and emerging silicon based materials and devices. The synthetic tunability and diversity of properties of organic molecules suggests a range of promising applications for the resulting hybrid organic/silicon structures. At the simplest level, molecular monolayer...
متن کاملIntrinsic magnetism at silicon surfaces.
It has been a long-standing goal to create magnetism in a non-magnetic material by manipulating its structure at the nanoscale. Many structural defects have unpaired spins; an ordered arrangement of these can create a magnetically ordered state. In this article we predict theoretically that stepped silicon surfaces stabilized by adsorbed gold achieve this state by self-assembly, creating chains...
