ARPES experiment in fermiology of quasi-2D metals (Review Article) A. A. Kordyuka) G.V. Kurdyumov Institute of Metal Physics of the National Academy of Sciences of Ukraine, ARPES is an emerging tool for studying momentum-resolved electron structure in the reciprocal space of solid material surface and is comparable directly with theoretical band-structure calculations. With the successive increase of energy and momentum resolution, ARPES has become a sophisticated tool to study complex phenomena in quantum In this review, we first give a brief introduction of TQMs and ARPES, which is followed by examples of the application of ARPES to different TQMs ranging from topological insulators to Dirac and Weyl semimetals. We conclude with a brief perspective of the current development of ARPES and its potential application in the study of TQMs. We developed a table-top vacuum ultraviolet (VUV) laser with 113.778 nm wavelength (10.897 eV) and demonstrated its viability as a photon source for high resolution angle-resolved photoemission spectroscopy (ARPES). A comparative study of the gaps measured in two techniques, angle-resolved photoelectron spectroscopy and spectroscopic imaging scanning tunneling microscopy, is presented. In particular the study focuses on the more overdoped region of the cuprate phase diagram in the superconducting state. While the total densities of states measured in the two techniques agree very well, it is shown that ARPES has been used to visualize electronic structures of various 3D TIs such as Bi 1−x Sb x alloy, 55, 61 V 2-VI 3 binary compounds (Bi 2 Te 3, Bi 2 Se 3, and Sb 2 Te 3), 56, 60, 90, 91 and the ternary III-V-VI 2 family of compounds.

ARPES experiment in fermiology of quasi-2D metals (Review Article

A distinct phenomenology between the near-nodal and the near-antinodal region of the Brillouin zone is observed, and this is interpreted in terms of a 'two gap' picture, where the pseudogap is a distinct electronic phase from superconductivity, with the two coexisting below T c . A series of angle-resolved photoemission spectroscopy (ARPES) studies were performed to understand the origin of the nematic phase. However, there is lack of ARPES study on LaFeAsO nematic phase I05-ARPES is a facility dedicated to the study of electronic structures of solids and their surfaces by Angle-Resolved Photoemission Spectroscopy (ARPES). The ultra-high vacuum low temperature high resolution ARPES end station is served by an intense, highly monochromatic VUV to XUV photon beam from a variable polarisation Apple II undulator. Angle-resolved photoemission spectroscopy (ARPES) enables direct observation of the Fermi surface and underlying electronic structure of crystals, which are the basic concepts necessary to describe all the electronic properties of solids and to reveal the nature of key electronic interactions involved.
