Angle-Resolved Photoemission Spectroscopy
Angle-Resolved Photoemission Spectroscopy (ARPES) is one type of photoemission spectroscopies to obtain information about the electronic band structure and Fermi surface of crystals in the reciprocal space. Soft X-ray is irradiated onto the crystal surface, and the kinetic energy of photoelectrons emitted from the surface is measured as a function of polar and azimuthal angles. Because electrons escape from the surface are projected through the surface, the direction of the momentum perpendicular to the surface is not conserved. Therefore, ARPES is an ideal tool for 2D materials because the direction of the electronic momentum of interest is parallel to the surface. The increased sensitivity of excitations can be achieved by reducing thermal energy at cryogenic temperatures.
