Photo-electron has excess energy.

Explore the Photoelectric Effect involving alkali metal cylinders on a wheel, operating with an electromagnet. X-ray Photoelectron Spectroscopy (XPS), a surface-sensitive method, allows precise chemical analysis. Dive into the world of Angle-Resolved Photoemission and Ultraviolet Photoelectron Spectroscopy (UPS) for detailed insights.

Presentation Transcript

  1. Original CaptionThe Photoelectric Effect. Cylinders of alkali metal placed on wheel, W, kept clean by knife, K, operated by electromagnet, F. A beam of light, let in at O, falls on the surface. From Physical Review 7 (1916):362.

  2. Photo-electron has excess energy. Photo-electron is stopped.

  3. X-ray Photo Emission (XPS) X-Ray Electron Spectroscopy (XPS) or Electron Spectroscopy for Chemical Analysis (ESCA) is a surface sensitive method with a typical information depth of 1 - 5 nm corresponding to 4 - 20 atomic or molecular monolayers, determined by the mean free path of electrons. The imnaged and analyzed area varies between 2 - 500 um with a sensitivity limit of 0. 1- 1 % of a monolayer corresponding to 1012 - 1013 atoms/cm2 or 10-15 - 10-16 g within the analyzed volume. Angle-resolved photoemission
