Direct comparison between potential landscape and local density of states in a disordered two-dimensional electron system
M. Morgenstern, J. Klijn, Chr. Meyer +7
The local density of states (LDOS) of the adsorbate induced two-dimensional electron system (2DES) on n-InAs(110) is studied by low-temperature scanning tunneling spectroscopy. The…
Vacuum space charge effect in laser-based solid-state photoemission spectroscopy
J. Graf, S. Hellmann, C. Jozwiak +6
We report a systematic measurement of the space charge effect observed in the few-ps laser pulse regime in laser-based solid-state photoemission spectroscopy experiments. The broad…
Angle resolved photoemission spectroscopy of Sr_2CuO_2Cl_2 - a revisit
C. Duerr, S. Legner, R. Hayn +16
We have investigated the lowest binding-energy electronic structure of the model cuprate Sr_2CuO_2Cl_2 using angle resolved photoemission spectroscopy (ARPES). Our data from about…
Ultrafast melting of a charge-density wave in the Mott insulator 1T-TaS2
S. Hellmann, M. Beye, C. Sohrt +11
Femtosecond time-resolved core-level photoemission spectroscopy with a free-electron laser is used to measure the atomic-site specific charge-order dynamics in the charge-density-w…
How to determine Fermi vectors by angle resolved photoemission?
L. Kipp, K. Rossnagel, J. Brugmann +4
Angle resolved photoemission spectroscopy (ARPES) has been commonly applied to evaluate the shape of Fermi surfaces by employing simple criteria for the determination of the Fermi…
Energetic and spatial bonding properties from angular distributions of ultraviolet photoelectrons: application to the GaAs(110) surface
C. Solterbeck, W. Schattke, J. -W. Zahlmann-Nowitzki +5
Angle-resolved ultraviolet photoemission spectra are interpreted by combining the energetics and spatial properties of the contributing states. One-step calculations are in excelle…
