Description

Angle-resolved photoemission spectroscopy (ARPES), is a direct experimental technique to observe the distribution of the electrons (more precisely, the density of single-particle electronic excitations) in the reciprocal space of solids. The technique is a refinement of ordinary photoemission spectroscopy, studying photoemission of electrons from a sample achieved usually by illumination with soft X-rays. ARPES is one of the most direct methods of studying the electronic structure of the surface of solids.

The topic of this two-days workshop would be as follows:

  • Introduction to the Electronic Structure of Solids
  • Ultra-High Vacuum Techniques and Chamber (UHV)
  • Theory of Angle-Resolved Photoemission Spectroscopy (ARPES)
  • ARPES Helium Lamp Chamber
  • ARPES Measurements on 2D Structure: Graphene and Topological Insulators
  • Step by Step Procedure for an Experiment by ARPES
  • The Electronic Structure of High-Tc Cuprates ARPES Data Analysis
