Helium-3 cryostats for ARPES “Wet” and “Dry” Models availableAngle-Resolved Photoemission Spectroscopy (ARPES) is used to study the electronic structure of the surface of solids. The ARPES technique employs a synchrotron or laser beam to interact with a sample, resulting in emission of photoelectrons. By analyzing the energy and momentum of the photoelectrons, the Fermi surface […]
