Fe thin-film growth on Au(100): A self-surfactant effect and its limitations

Fe thin-film growth on Au„100...: A self-surfactant effect and its limitations

The combination of low-energy electron diffraction intensity analyses and scanning tunneling microscopy was used to investigate the morphology and atomic structure of thin Fe films grown on Au~100! at 400 K. Deposition of only about 0.2 monolayers ~ML! Fe is sufficient to lift the reconstruction of the clean substrate. In the initial growth process (<1 ML! place exchanges between Fe and Au lead...

The surfactant effect in semiconductor thin film growth

an investigation of the impact of self monitoring on langauge teachers motivational practice and its effect on learners motivation

the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...

Surfactant spreading on a thin liquid film: reconcilingmodels and experiments

The spreading dynamics of surfactant molecules on a thin fluid layer is of both fundamental and practical interest. A mathematical model formulated by Gaver and Grotberg [J Fluid Mech 235:399–414, 1992] describing the spreading of a single layer of insoluble surfactant has become widely accepted, and several experiments on axisymmetric spreading have confirmed its predictions for both the heigh...

Computer simulation of surfactant-mediated thin film growth*

A novel model consisting of basic micro-processes has been developed on the basis of the classic diffusion theory. It is first time that the concept of exchange rate has been introduced and the growing process of surfactant-mediated epitaxial thin-film growth has been simulated with Kinetic Monte Carlo (KMC) technique. The results of simulation found that the exchange reaction of RLA model is a...
