Workshop on: Probing the Electronic Structure of Solids by Angle-resolved photoemission spectroscopy (ARPES)

25 Apr 2016, 08:00 → 26 Apr 2016, 18:00 Asia/Tehran

Faculty of Materials Science Technology (K.N.Toosi University of Technology)

AliAkbar Ghafari (Helmholtz-Zentrun), Christoph Janowitz (Humboldt University), Luca Petaccia (Elettra Synchrotron)

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
