Lithographically-controlled liquid metal diffusion in graphene: Fabrication and magneto-transport signatures of superconductivity
S. Wundrack, M. Bothe, M. Jaime +15
Metal intercalation in epitaxial graphene enables the emergence of proximity-induced superconductivity and modified quantum transport properties. However, systematic transport stud…
Growth dynamics of graphene buffer layer formation on ultra-smooth SiC(0001) surfaces
Julia Guse, Stefan Wundrack, Marius Eckert +14
In this study the growth process of epitaxial graphene on SiC was investigated systematically. The transition from the initial buffer layer growth to the formation of the first mon…
Homogeneous doping of epitaxial graphene by Pb(111) islands: A magnetotransport study
Julian Koch, Sergii Sologub, Dorothee Sylvia Boesler +5
Proximity coupling is an effective approach for the functionalization of graphene. However, graphene's inertness inhibits the adsorption of closed films, thus favoring island growt…
Observation of Floquet states in graphene
Marco Merboldt, Michael Schüler, David Schmitt +11
Recent advances in the field of condensed-matter physics have unlocked the potential to realize and control emergent material phases that do not exist in thermal equilibrium. One o…
Enhanced Shot Noise in Tunneling through a Stack of Coupled Quantum Dots
P. Barthold, F. Hohls, N. Maire +2
We have investigated the noise properties of the tunneling current through vertically coupled self-assembled InAs quantum dots. We observe super-Poissonian shot noise at low temper…
Shot noise in self-assembled InAs quantum dots
A. Nauen, I. Hapke-Wurst, F. Hohls +3
We investigate the noise properties of a GaAs-AlAs-GaAs tunneling structure with embedded self-assembled InAs quantum dots in the single-electron tunneling regime. We analyze the d…
High frequency conductivity in the quantum Hall effect
F. Hohls, U. Zeitler, R. J. Haug +1
We present high frequency measurements of the diagonal conductivity sigma_xx of a two dimensional electron system in the integer quantum Hall regime. The width of the sigma_xx peak…
