PINTA – Clean Surface 2002-2006
The Control of small-particle surface forces and initial stages of surface oxidation (SURFOX) project focuses on the adhesion forces between small particles of oxide/silica and oxide or metal surfaces. The adhesion force between silica particles and a titania surface is at its minimum when the surface roughness of both materials is about the same. The goal of this first part was to understand u...
متن کاملSurface Characterization of Clean Gd5Ge4(010)
Based on X-ray photoelectron spectroscopy, Gd5Ge 4(010) does not show evidence of surface segregation. Scanning tunneling microscopy reveals two types of terraces which alternate laterally on the surface. From the step heights, these two surface terminations are assigned as dense, Gd-pure layers in the bulk structure. There is evidence of reconstruction on one type of terrace.
متن کاملStructure of the clean Gd5Ge4(010) surface.
We have characterized the (010) surface of Gd5Ge4 using scanning tunneling microscopy (STM) and x-ray photoelectron spectroscopy. Data from different samples have the following features in common: (1) the surface composition equals the bulk composition to within 5 at.%, both after ion etching and after annealing at temperatures of 400-1200 K; and (2) the surface exhibits terraces of two types. ...
متن کاملStudy of Ultra-clean Surface for Niobium SC Cavities
For a TeV energy particle physics, R&D of electron/positron linear colliders has been conducted very hard at many laboratories. Development of high field gradient cavities is one of key issues to realize such a machine. Field emission loading is a dominant phenomenon limiting high field. Particulate contamination on the inner surface is a main source of field emission. In this paper, we report ...
متن کاملSTRUCTURE DETERMINATION OF THE CLEAN Co(1120) SURFACE BY LEED
The atomic structure of the (1120) surface of cobalt has been determined by LEED using six intensity spectra at normal incidence. The surface exhibits the truncated bulk structure with a contraction of the first interlayer spacing by about 8.5% with respect to the bulk value. Quantitative evaluation of the LEED spectra was done using Zanazzi and Jona’s and Pendry’s r-factors. The minimum averag...
