Random strain fluctuations as dominant disorder source for high-quality on-substrate graphene devices
Nuno J. G. Couto, Davide Costanzo, Stephan Engels +6
We have performed systematic investigations of transport through graphene on hexagonal boron nitride (hBN) substrates, together with confocal Raman measurements and a targeted theo…
In-plane electronic confinement in superconducting LaAlO/SrTiO nanostructures
D. Stornaiuolo, S. Gariglio, N. J. G. Couto +6
We describe the transport properties of mesoscopic devices based on the two dimensional electron gas (2DEG) present at the LaAlO/SrTiO interface. Bridges with lateral dimen…
Transport through graphene on SrTiO3
N. J. G. Couto, B. Sacepe, A. F. Morpurgo
We report transport measurements through graphene on SrTiO3 substrates as a function of magnetic field B, carrier density n, and temperature T. The large dielectric constant of SrT…
Gate-tuned normal and superconducting transport at the surface of a topological insulator
B. Sacepe, J. B. Oostinga, J. Li +4
Three-dimensional topological insulators are characterized by the presence of a bandgap in their bulk and gapless Dirac fermions at their surfaces. New physical phenomena originati…
Controllable transport mean free path of light in xerogel matrixes embedded with polystyrene spheres
Boris P. J. Bret, Nuno J. G. Couto, Mariana Amaro +2
Xerogel matrices, made by sol-gel techniques, are embedded with polystyrene spheres to promote multiple scattering of light. Varying the concentration of the spheres inside the mat…
