Phonons in Ultrathin Oxide Films: 2D to 3D Transition in FeO on Pt(111).
The structural and magnetic properties of ultrathin FeO(111) films on Pt(111) with thicknesses from 1 to 16 monolayers (MLs) were studied using the nuclear inelastic scattering of synchrotron radiation. A distinct evolution of vibrational characteristics with thickness, revealed in the phonon density of states (PDOS), shows a textbook transition from 2D to 3D lattice dynamics. For the thinnest ...
متن کاملDeconvoluted Si 2p Photoelectron Spectra of Ultra thin SiO2 film with FitXPS method
The main impetus for our research is provided by the growing interest worldwide in ultra thin silicon dioxide on silicon based nano devices. The obvious need for better knowledge in the ultra thin gate silicon dioxides, is motivated both by interests in fundamental research and phenomenology as well as by interests in possible applications, which can be found with better fitting of experimental...
متن کاملThermal Oxidation Times Effect on Structural and Morphological Properties of Molybdenum Oxide Thin Films Grown on Quartz Substrates
Molybdenum oxide (α-MoO)thin films were prepared on quartz and silicon substrates by thermal oxidation of Mo thin films deposited using DC magnetron sputtering method. The influence of thermal oxidation times ranging from 60-240 min on the structural and morphological properties of the preparedfilms was investigated using X-ray diffraction, Atomic force microscopy and Fourier transform infrared...
متن کاملساخت و بررسی نمونههای حجمی و لایه نازک فریت استرانسیوم
In this article, bulk and thin film samples of strontium ferrite have been studied. Due to the high electrical resistivity in strontium ferrite, energy loss due to eddy currents reduces and because of this, it can be used in high frequency magnetic circuits. On the other hand, strontium ferrite has attracted much attention as a permanent magnet. At first, we study the preparation process of b...
متن کاملSelf-organization of gold atoms on a polar FeO(111) surface.
The spatial distribution of single Au atoms on a thin FeO film has been investigated by low-temperature scanning tunneling microscopy and spectroscopy. The adatoms preferentially adsorb on distinct sites of the Moiré cell formed by the oxide layer and the Pt(111) support and arrange into a well-ordered hexagonal superlattice with 25 angstroms lattice constant. The self-organization is the conse...
