ARPES in strongly disordered systems -- theory of electronic bands melting
Piotr Chudzinski, Lenart Dudy
It is well known that translational symmetry-breaking disorder will disrupt ARPES spectra up to the point where they become invisible. However, a theoretical framework to capture t…
Temperature dependent ARPES of the metallic-like bands in Si(553)-Au
Lenart Dudy, Julian Aulbach, Jörg Schäfer +3
We conducted a thorough investigation into the temperature dependence of the metallic-like bands of Si(553)-Au using angular-resolved photoemission spectroscopy (ARPES). Our study…
Toward Functionalized Ultrathin Oxide Films: the Impact of Surface Apical Oxygen
Judith Gabel, Matthias Pickem, Philipp Scheiderer +12
Thin films of transition metal oxides open up a gateway to nanoscale electronic devices beyond silicon characterized by novel electronic functionalities. While such films are commo…
Hard x-ray angle-resolved photoemission from a buried high-mobility electron system
Michael Zapf, Matthias Schmitt, Judith Gabel +18
Novel two-dimensional electron systems at the interfaces and surfaces of transition-metal oxides recently have attracted much attention as they display tunable, intriguing properti…
Tailoring the topological surface state in ultrathin -Sn (111) films
Victor A. Rogalev, Felix Reis, Florian Adler +11
We report on the electronic structure of -Sn films in the very low thickness regime grown on InSb(111)A. High-resolution low photon energies angle-resolved photoemission (ARPES)…
Wannier-Orbital theory and ARPES for the quasi-1D conductor LiMoO
L. Dudy, J. W. Allen, J. D. Denlinger +5
In this set of three papers, we present the results of a combined study by density-functional (LDA) band theory (NMTO) and angle-resolved photoemission spectroscopy (ARPES) of lith…
