Decoration Technique

Besides the atomic surface structure, diverging in special cases with respect to the bulk structure, the real structure of a surface Is determined by the step structure. Using the decoration technique /1/ it is possible to image step structures having step heights down to a single lattice plane distance electron-microscopically. For a number of problems the knowledge of the monatomic step structures is important, because numerous problems of surface physics are directly connected with processes taking place at these steps, e.g. crystal growth or evaporation, sorption and nucleatlon as initial stage of overgrowth of thin films.To demonstrate the decoration technique by means of evaporation of heavy metals Fig. 1 from our former investigations shows the monatomic step structure of an evaporated NaCI crystal. of special Importance Is the detection of the movement of steps during the growth or evaporation of a crystal. From the velocity of a step fundamental quantities for the molecular processes can be determined, e.g. the mean free diffusion path of molecules.

AbstractIn this paper I analyse the most important pieces of evidence concerning the structure of Middle Platonist exegesis (passages from Diogenes Laertius, Taurus of Beirut, the anonymous Commentary on the Theaetetus, Longinus). At first sight these sources seem to present a two-step structure in Middle Platonist exegesis, i. e. a structure which would be quite similar to the Neoplatonic λέξις–θεωρία model. I shall argue, however, that this is not the case: such a structure could be ascribed (in different arrangements) to school exegetical praxis, but it was not applied in Middle Platonist exegetical writings, which were not bound to specific stylistic patterns.

Writing is a challenging and demanding skill for EFL learners in Vietnam. Teaching writing skills at Vietnamese universities is problematic since different approaches to writing have not been implemented effectively. Mainly, a genre-based approach to writing has not yet been implemented in EFL writing classrooms successfully. This paper investigates how the genre-based writing approach has been taught and learned at Van Lang University. The study mentions some critical notions of systemic functional linguistics, genre-based writing approach, and the importance and effects of genre-based approach to writing. 128 students turned in their midterm essays in week 5 of the 10-week writing course. These 128 expository essays were analyzed and synthesized using Microsoft Excel to calculate the differences in move-step structure. The findings indicated that the students had difficulty following the fixed move-step structure, and they also faced challenges of lexico-grammatical usage for the expository. Hence, the study suggests some implications for applying a genre-based approach to writing for EFL teachers and students and suggests further research.
