Coulomb blockade in microscopic material defects as a source of decoherence and noise in solid-state quantum circuits

R. Banerjee, L. P. Lindoy, M. Hegedus +9

A critical limitation of solid-state quantum devices arises from the materials from which they are fabricated: uncontrolled surfaces, interfaces, and structural imperfections intro…

Mapping quantum Hall edge states in graphene by scanning tunneling microscopy

T. Johnsen, C. Schattauer, S. Samaddar +7

Quantum Hall edge states are the paradigmatic example of the bulk-boundary correspondence. They are prone to intricate reconstructions calling for their detailed investigation at h…

Evidence for local spots of viscous electron flow in graphene at moderate mobility

Sayanti Samaddar, Jeff Strasdas, Kevin Janßen +8

Dominating electron-electron scattering enables viscous electron flow exhibiting hydrodynamic current density patterns such as Poiseuille profiles or vortices. The viscous regime h…

Modulating charge density and inelastic optical response in graphene by atmospheric pressure localized intercalation through wrinkles

Amina Kimouche, Olivier Renault, Sayanti Samaddar +4

The intercalation of an oxide barrier between graphene and its metallic substrate for chem- ical vapor deposition is a contamination-free alternative to the transfer of graphene to…

Niobium-based superconducting nano-devices fabrication using all-metal suspended masks

S. Samaddar, D. van Zanten, A. Fay +3

We report a novel method for the fabrication of superconducting nanodevices based on niobium. The well-known difficulties of lithographic patterning of high-quality niobium are ove…

Ripples and Charge Puddles in Graphene on a Metallic Substrate

S. C. Martin, S. Samaddar, B. Sacépé +6

Graphene on a dielectric substrate exhibits spatial doping inhomogeneities, forming electron-hole puddles. Understanding and controlling the latter is of crucial importance for unr…
