Probing graphene χ(2) using a gold photon sieve
Michael Lobet, Michael Sarrazin, Francesca Cecchet +4
Nonlinear second harmonic optical activity of graphene covering a gold photon sieve was determined for different polarizations. The photon sieve consists of a subwavelength gold na…
Graphene-coated holey metal films: tunable molecular sensing by surface plasmon resonance
Nicolas Reckinger, Alexandru Vlad, Sorin Melinte +2
We report on the enhancement of surface plasmon resonances in a holey bidimensional grating of subwavelength size, drilled in a gold thin film coated by a graphene sheet. The enhan…
Dephasing Time of Two-Dimensional Holes in GaAs Open Quantum Dots
S. Faniel, B. Hackens, A. Vlad +6
We report magnetotransport measurements of two-dimensional holes in open quantum dots, patterned either as a single-dot or an array of dots, on a GaAs quantum well. For temperature…
Thermopower of Interacting GaAs Bilayer Hole Systems in the Reentrant Insulating Phase near
S. Faniel, E. Tutuc, E. P. De Poortere +5
We report thermopower measurements of interacting GaAs bilayer hole systems. When the carrier densities in the two layers are equal, these systems exhibit a reentrant insulating ph…
