Resonant Dyakonov-Shur Magnetoplasmons in Graphene Terahertz Photodetectors
Juan A. Delgado-Notario, Cedric Bray, Elsa Perez-Martin +16
Graphene plasmons confine incident terahertz fields far below the diffraction limit and, when hosted by a gate-defined Fabry-Perot cavity, enable electrically tunable, frequency-se…
Systematic investigation of the generation of luminescent emitters in hBN via irradiation engineering
Pooja C. Sindhuraj, José M. Caridad, Corné Koks +9
Hexagonal boron nitride (hBN), a two-dimensional (2D) material, garners interest for hosting bright quantum emitters at room temperature. A great variety of fabrication processes h…
Enhanced and Spectrally Selective Near Infrared Photothermal Conversion in Plasmonic Nanohelices
Juan A. Delgado-Notario, David López-Díaz, David McCloskey +1
We study the photothermal conversion in plasmonic nanohelices, unveiling how helical nanostructures made from metals with a notable interband activity, such as cobalt (Co) and nick…
Spin-dependent photovoltage in graphene/MoS2-based field-effect transistors
K. Dinar, J. Delgado-Notario, C. Bray +14
It has recently been shown that Terahertz sensors can effectively detect the spin resonances of Dirac fermions in graphene. The associated photovoltaic measurement technique allows…
Room-Temperature Plasmon-Assisted Resonant THz Detection in Single-layer Graphene Transistors
José M. Caridad, Óscar Castelló, Sofía M. López Baptista +4
Frequency-selective or even frequency-tunable Terahertz (THz) photodevices are critical components for many technological applications that require nanoscale manipulation, control…
Phonon-mediated room-temperature quantum Hall transport in graphene
Daniel Vaquero, Vito Clericò, Michael Schmitz +14
The quantum Hall (QH) effect in two-dimensional electron systems (2DESs) is conventionally observed at liquid-helium temperatures, where lattice vibrations are strongly suppressed…
Temperature Dependent Zero-Field Splittings in Graphene
C. Bray, K. Maussang, C. Consejo +15
Graphene is a quantum spin Hall insulator with a 45 eV wide non-trivial topological gap induced by the intrinsic spin-orbit coupling. Even though this zero-field spin splitting…
Generation and control of non-local chiral currents in graphene superlattices by orbital Hall effect
Juan Salvador-Sánchez, Luis M. Canonico, Ana Pérez-Rodríguez +15
Graphene-based superlattices offer a new materials playground to exploit and control a higher number of electronic degrees of freedom, such as charge, spin, or valley for disruptiv…
Quantum nanoconstrictions fabricated by cryo-etching in encapsulated graphene
Vito Clericò, Juan Antonio Delgado-Notario, Marta Saiz-Bretín +7
More than a decade after the discovery of graphene, ballistic transport in nanostructures based on this intriguing material still represents a challenging field of research in two-…
Quantized electron transport through graphene nanoconstrictions
V. Clerico, J. A. Delgado-Notario, M. Saiz-Bretin +5
We study the quantization of Dirac fermions in lithographically defined graphene nanoconstrictions. We observe quantized conductance in single nanoconstrictions fabricated on top o…
