This book was released on 2003-07-21 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the rapid increase in commercially available Fouriertransform infrared spectrometers and computers over the past tenyears, it has now become feasible to use IR spectrometry tocharacterize very thin films at extended interfaces. At the sametime, interest in thin films has grown tremendously because ofapplications in microelectronics, sensors, catalysis, andnanotechnology. The Handbook of Infrared Spectroscopy of UltrathinFilms provides a practical guide to experimental methods,up-to-date theory, and considerable reference data, critical forscientists who want to measure and interpret IR spectra ofultrathin films. This authoritative volume also: Offers informationneeded to effectively apply IR spectroscopy to the analysis andevaluation of thin and ultrathin films on flat and rough surfacesand on powders at solid-gaseous, solid-liquid, liquid-gaseous,liquid-liquid, and solid-solid interfaces. Provides full discussion of theory underlying techniques Describes experimental methods in detail, including optimumconditions for recording spectra and the interpretation ofspectra Gives detailed information on equipment, accessories, andtechniques Provides IR spectroscopic data tables as appendixes, includingthe first compilation of published data on longitudinal frequenciesof different substances Covers new approaches, such as Surface Enhanced IR spectroscopy(SEIR), time-resolved FTIR spectroscopy, high-resolutionmicrospectroscopy and using synchotron radiation

This book was released on 2018 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon and metal surfaces modified with organic molecule precursors are of great importance to the semiconductor and electronics industries. However, it is always a challenge to choose the most efficient precursors for forming a monolayer with surfaces and to investigate the chemical changes on surfaces by controlling critical conditions, such as surface temperature. In order to obtain a better understanding of the reactions between organic molecules and surfaces, we combined experimental results including infrared spectroscopy (IR), temperature programmed desorption (TPD), X-ray photoelectron spectroscopy (XPS), and microscopic studies together with density functional theory (DFT) studies. For silicon surface studies, we focused on determining the reaction step that plays the key role in halide precursors sticking probabilities and the influence of temperature on the formed monolayer. For metal surface studies, we focused on the etching method to control the layer thickness of thin metal films. ☐ During the process of achieving a halide-terminated Si (100) surface in ultrahigh vacuum (UHV), we compared the sticking probabilities of ethyl-chloride and ethyl-iodide reacting with a clean Si (100) surface using TPD and DFT studies. It has been demonstrated that the weakly bound precursor states of ethyl-halide on surfaces determines the sticking probabilities during adsorption. At the same time, we applied multivariate curve resolution (MCR), a mathematical method to simplify interpreting the complex TPD spectra resulting from the low sticking probability of ethyl-chloride adsorbing on silicon surfaces. ☐ In addition to halide-terminated Si (100) surfaces, amine-terminated Si (100) surfaces are reactive and potential for further modification. We studied the adsorption of triethylenediamine (TEDA) on a clean Si (100) surface as well as the adsorbents while varying temperature. The experimental techniques including IR, TPD, XPS and angular dependent near-edge X-Ray adsorption fine structure (NEXAFS) were supplemented by DFT calculations. We concluded that the adsorption process can be controlled by temperature: a datively bonded TEDA-Si-Si complex forms on the surface at room temperature as well as at cryogenic temperature with low exposure; heating above 400 K leads to C-N dissociation and ultimately the formation of surface nitride and carbide species. ☐ A thermal dry etching process of cobalt thin films was investigated using 1, 1, 1, 5, 5, 5 -hexafluoro-2, 4-pentanedione (hfacH). The chemical species resulting from thermal treatment were studied by IR, TPD, and XPS. The topography and morphology of the surfaces were investigated by atomic force microscopy (AFM) and scanning electron microscopy (SEM). The results indicated that the etching of cobalt can occur Hhfac, but not with halogens.

Available in PDF, EPUB and Kindle. Book excerpt: Experimental advances in helium atom scattering spectroscopy over the last forty years have allowed the measurement of surface phonon dispersion curves of more than 200 different crystal surfaces and overlayers of insulators, semiconductors and metals. The first part of the book presents, at a tutorial level, the fundamental concepts and methods in surface lattice dynamics, and the theory of atom-surface interaction and inelastic scattering in their various approximations, up to the recent electron-phonon theory of helium atom scattering from conducting surfaces. The second part of the book, after introducing the experimentalist to He-atom spectrometers and the rich phenomenology of helium atom scattering from corrugated surfaces, illustrates the most significant experimental results on the surface phonon dispersion curves of various classes of insulators, semiconductors, metals, layered crystals, topological insulators, complex surfaces, adsorbates, ultra-thin films and clusters. The great potential of helium atom scattering for the study of atomic scale diffusion, THz surface collective excitations, including acoustic surface plasmons, and the future prospects of helium atom scattering are presented in the concluding chapters. The book will be valuable reading for all researchers and graduate students interested in dynamical processes at surfaces.
