Apparent rippling with honeycomb symmetry and tunable periodicity observed by scanning tunneling microscopy on suspended graphene
A. Georgi, P. Nemes-Incze, B. Szafranek +4
Suspended graphene is difficult to image by scanning probe microscopy due to the inherent van-der-Waals and dielectric forces exerted by the tip which are not counteracted by a sub…
Probing the nodal structure of Landau level wave functions in real space
J. R. Bindel, J. Ulrich, M. Liebmann +1
The inversion layer of p-InSb(110) obtained by Cs adsorption of 1.8 % of a monolayer is used to probe the Landau level wave functions within smooth potential valleys by scanning tu…
Preferential antiferromagnetic coupling of vacancies in graphene on SiO_2: Electron spin resonance and scanning tunneling spectroscopy
S. Just, S. Zimmermann, V. Kataev +3
Monolayer graphene grown by chemical vapor deposition and transferred to SiO_2 is used to introduce vacancies by Ar^+ ion bombardment at a kinetic energy of 50 eV. The density of d…
Spin properties of 2D semiconductors probed by scanning tunneling microscopy
M. Morgenstern, A. Georgi, C. Straßer +3
The interrelation between spin and charge in semiconductors leads to interesting effects, e.g., the Rashba-type spin-orbit splitting or the exchange enhancement. These properties a…
Catalytic Growth of N-doped MgO on Mo(001)
M. Grob, M. Pratzer, M. Ležaić +1
A simple pathway to grow thin films of N-doped MgO (MgO:N), which has been found experimentally to be a ferromagnetic d0 insulator, is presented. It relies on the catalytic propert…
Robust Nodal Structure of Landau Level Wave Functions Revealed by Fourier Transform Scanning Tunneling Spectroscopy
K. Hashimoto, T. Champel, S. Florens +6
Scanning tunneling spectroscopy is used to study the real-space local density of states (LDOS) of a two-dimensional electron system in magnetic field, in particular within higher L…
Wave function mapping in graphene quantum dots with soft confinement
D. Subramaniam, F. Libisch, Y. Li +11
Using low-temperature scanning tunneling spectroscopy, we map the local density of states (LDOS) of graphene quantum dots supported on Ir(111). Due to a band gap in the projected I…

Using low-temperature scanning tunneling spectroscopy applied to the Cs-induced two-dimensional electron system (2DES) on p-type InSb(110), we probe electron-electron interaction e…
Gundlach oscillations and Coulomb blockade of Co nano-islands on MgO/Mo(100) investigated by scanning tunneling spectroscopy at 300 K
C. Pauly, M. Grob, M. Pezzotta +2
Ultrathin MgO films on Mo(100) with a thickness up to 12 ML are studied by scanning tunneling microscopy and spectroscopy at room temperature. The spatial variation of the work fun…
Electrical transport and low-temperature scanning tunneling microscopy of microsoldered graphene

T. Mashoff, M. Pratzer, V. Geringer +4
The recently found material graphene is a truly two-dimensional crystal and exhibits, in addition, an extreme mechanical strength. This in combination with the high electron mobili…
The Quantum Hall Transition in Real Space: From Localized to Extended States
K. Hashimoto, C. Sohrmann, J. Wiebe +6
Using scanning tunneling spectroscopy in ultra-high vacuum at low temperature (T = 0.3 K) and high magnetic fields (B < 12 T), we directly probe electronic wave functions across an…
