WHAT: Beyond the Surface: Design and Applications of a New Laboratory-Based Scanning XPS/HAXPES Instrument
WHERE: Hyatt Regency Hotel - Delaware Room A
X-ray Photoelectron Spectroscopy (XPS) is a widely used surface analysis technique with many well established industrial and research applications. The surface sensitivity (top 5-10 nm) of XPS and its ability to provide short-range chemical bonding information make the technique extremely popular in materials characterization and failure analysis laboratories. In some instances, an increased depth of analysis is desired over what can be obtained using XPS. Sputter etching can be performed to analyze below the surface; however, sputtering can often damage the chemistry of interest. An alternative is to use Hard X-ray Photoelectron Spectroscopy (HAXPES), traditionally only available at some synchrotron facilities. HAXPES utilizes X-rays typically defined as having energies greater than 5 keV. Depending on the energy used, these hard X-rays can provide depths of analysis 3 or more times that of soft x-rays used on conventional XPS systems. HAXPES measurements are therefore more sensitive to the bulk, and contributions from the surface are minimized.
This presentation will describe a newly developed laboratory-based instrument, the PHI Quantes, equipped with two scanning microprobe monochromated X-ray sources, Al Kα (1486.6 eV) and Cr Kα (5414.9 eV), thus enabling both traditional XPS and HAXPES experiments in the same instrument. Probing multiple depths of analysis without sputter etching opens new capabilities for probing the composition of buried layers and interfaces. A variety of applications showing the utility of combining the two X-ray sources will be shown.
