Description

X-ray Photoelectron Spectroscopy (XPS), also known as Electron Spectroscopy for Chemical Analysis (ESCA), is a powerful research tool for the study of the physical and chemical properties of a material's surface. XPS uses a beam of X-rays to irradiate the material while simultaneously measuring the kinetic energy (KE) and the number of electrons that escape from within the top 10 to 12 nm of the material being analyzed. The resulting spetra of number of electrons vs. the kinetic energy is used to identify the elements present on the surface of the material being analyzed. For a more extensive description of XPS see WIkipedia.

  1. Mystery Molecules: Identifying Materials with Nanoscale Characterization Tools

    Teaching Materials | 18 Mar 2020 | Contributor(s):: Maude Cuchiara, NNCI Nano

     In this lesson plan, students will be given several similar looking materials and asked to identify them by observing them at the macro and micro-scale. They will then be exposed to different analytical tools and describe how they can be used to explore materials at the nanoscale. ...

  2. X-Ray Photoelectron Spectroscopy (XPS)

    Teaching Materials | 14 Dec 2006 | Contributor(s):: David Echevarria Torres

    The XPS (X-Ray Photoelectron Spectroscopy) it is also known as ESCA (Electron Spectroscopy for Chemical Analysis). This technique is based on the theory of the photoelectric effect that was developed by Einstein, yet it was Dr. Siegbahn and his research group who developed the XPS technique. ...
