Photoemission electron spectroscopy (PES) is a powerful technique that provides information about chemical composition and electronic structure of a material surface. In this talk, the basic concepts and methods of PES will be introduced. The PES experiment facilities at the Siam Photon Laboratory, Synchrotron Light Research Institute (SLRI), will be overviewed. Examples for its applications...
The attractive properties of diamond-like carbon (DLC) films consist of chemical inertness, high hardness, excellent tribological behavior, optical properties, and biocompatibility.1,2 These properties make them reasonable for using in a broad range of the industrial applications. For example, the DLC films are used for magnetic storage disks, automotive parts, biomedical devices, cutting...
The investigation of the local geometric and electronic structure of probing element in bulk samples is the most extensive field of application in X-ray Absorption Spectroscopy (XAS). XAS consists of two main regions which are X-ray Absorption Near Edge Structure (XANES) and Extended X-ray Absorption Fine Structure (EXAFS). The former region is used to explain the local geometry and oxidation...
BL1.3W: SAXS/WAXS (Small/Wide angle x-ray scattering) at SLRI is a dedicated beamline for nano-structural investigation of material that has electron density fluctuation on the length scale under 100 nm. High intensity x-ray is obtained by incorporating the synchrotron radiation from a wiggler insertion device and a double multi-layers monochromator. The beam is focused by a toroidal mirror...
