Abstract

A simple model and computation of Moiré-regulated composition evolution kinetics of bicomponent nanoclusters is presented. Assuming continuous adsorbate coverage on top of 2D bilayer and Moiré potential-driven nanocluster formation at fcc sites of Moiré landscape, these sites experience the influx of one component of a bicomponent adsorbate and the outflux of another component. Kinetics of this process is characterized for several combinations of adsorption potentials and their relative strengths.

双组分纳米团簇的莫伊里调控成分演变动力学

本文提出了双组分纳米团簇的莫伊雷调控成分演变动力学的简单模型和计算方法。假定二维双分子层顶部有连续的吸附剂覆盖，莫伊里电位驱动纳米团簇在莫伊里地貌的 fcc 位点形成，这些位点会经历双组分吸附剂中一种组分的流入和另一种组分的流出。针对几种吸附电位组合及其相对强度，研究了这一过程的动力学特征。

期刊介绍： The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size. Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology. The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
