Functionalization of reduced graphite oxide sheets with a zwitterionic surfactant
Beatriz Martín-García, M. Mercedes Velázquez, Francesco Rossella +7
Films of a few layers in thickness of reduced graphite oxide, RGO, sheets functionalized by the zwitterionic surfactant N-dodecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate, DDPS, a…
Evidence for an excitonic insulator phase in a zero-gap InAs/GaSb bilayer
W. Yu, V. Clericò, C. Hernández Fuentevilla +16
Many-body interactions can produce novel ground states in a condensed-matter system. For example, interacting electrons and holes can spontaneously form excitons, a neutral bound s…
Magneto-transport of graphene and quantum phase transitions in the quantum Hall regime
Mario Amado, Enrique Diez, Francesco Rossella +3
We studied the magneto-transport in SiO2 substrate-supported monolayer graphene and the quantum phase transitions that characterize the quantum Hall regime, using magnetic fields u…
Circularly Polarized Resonant Rayleigh Scattering and Skyrmions in the = 1 Quantum Hall Ferromagnet
V. Bellani, F. Rossella, M. Amado +4
We use the circularly polarized resonant Rayleigh scattering (RRS) to study the quantum Hall ferromagnet at = 1. At this filling factor we observe a right handed copolarized RR…
Optical probing of correlation driven liquid-to-insulator transition in 2D electron gas
F. Dionigi, F. Rossella, V. Bellani +5
We study the quantum Hall liquid and the metal-insulator transition in a high mobility two dimensional electron gas, by means of photoluminescence and magneto-transport. In the int…
Plateau insulator transition in graphene
M. Amado, E. Diez, D. López-Romero +5
The quantum Hall effect in a single-layer graphene sample is studied in strong magnetic fields up to 28 T. Our measurements reveal the existence of a metal- insulator transition fr…
