Solid Surfaces, Interfaces and Thin Films

Abstract

Graduate Texts in Physics publishes core learning/teaching material for graduate-and advanced-level undergraduate courses on topics of current and emerging fields within physics, both pure and applied. These textbooks serve students at the MS-or PhD-level and their instructors as comprehensive sources of principles, definitions, derivations, experiments and applications (as relevant) for their mastery and teaching, respectively. International in scope and relevance, the textbooks correspond to course syllabi sufficiently to serve as required reading. Their didactic style, comprehensiveness and coverage of fundamental material also make them suitable as introductions or references for scientists entering, or requiring timely knowledge of, a research field.

Surface roughness analysis of SiO2 for PECVD, PVD and IBD on different substrates

“…So the substrate is not playing an important role in this matter, but while looking toward the Si wafer, it is observed that there is a difference in the value of surface roughness as compared to the other two substrates. The reason probably is the abrupt change in the interface between the substrate and the SiO film (crystalline/amorphous) (Lüth 2001) as compared to other substrates, i.e., glass and PEN, which has amorphous/amorphous interface.…”

Conductance oscillations of core-shell nanowires in transversal magnetic fields

“…Nanotubes of very narrow, but finite thickness may be achieved in few different ways. In the case of quantum wires built of narrow-gap materials surface states may induce Fermi level pinning above the conduction band edge which results in accumulation of electrons in the vicinity of the surface [1]. Nowadays it has become feasible to combine two (or even more) different materials into one vertical structure, i.e., coreshell nanowires (CSNs).…”

Development of an Ultrafast Low-Energy Electron Diffraction Setup

“…Specifically, the reciprocal lattice vectors, a * i , are defined in terms of the real space lattice vectors, a i , by the following relationship [1]:…”

“…Fig. B.1B, lower 1 Single layers of graphene are visible under the optical microscope when deposited on oxidized Si substrates with very defined thickness. In this case, single carbon layers can be distinguished by slightly changing the optical path length of the transmitted light in comparison to the empty substrate.…”

“…On the other hand, ultrafast time resolution 1 has been successfully implemented 1 Here, the term ultrafast is used for timescales below one nanosecond. in a number of systems for bulk analysis, including time-resolved electron [30] and xray spectroscopy [31,32], ultrafast electron diffraction (UED) [33][34][35] and microscopy [36][37][38], time-resolved second harmonic and sum frequency spectroscopy [39], as well as ultrafast x-ray crystallography [40,41].…”
