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…
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…
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…
Fermi velocity renormalization in graphene probed by terahertz time-domain spectroscopy
Patrick R. Whelan, Qian Shen, Binbin Zhou +13
We demonstrate terahertz time-domain spectroscopy (THz-TDS) to be an accurate, rapid and scalable method to probe the interaction-induced Fermi velocity renormalization νF^* of cha…
Electrostatics of metal-graphene interfaces: sharp p-n junctions for electron-optical applications
Ferney A. Chaves, David Jimenez, Jaime E. Santos +2
Creation of sharp lateral p-n junctions in graphene devices, with transition widths well below the Fermi wavelength of graphene charge carriers, is vital to study and exploit these…
Gate electrostatics and quantum capacitance in ballistic graphene devices
José M. Caridad, Stephen R. Power, Artsem A. Shylau +3
We experimentally investigate the charge induction mechanism across gated, narrow, ballistic graphene devices with different degrees of edge disorder. By using magnetoconductance m…
A Two-dimensional Dirac fermion microscope
Peter Bøggild, Jose M. Caridad, Christoph Stampfer +3
The electron microscope has been a powerful, highly versatile workhorse in the fields of material and surface science, micro and nanotechnology, biology and geology, for nearly 80…
The hot pick-up technique for batch assembly of van der Waals heterostructures
Filippo Pizzocchero, Lene Gammelgaard, Bjarke Sørensen Jessen +5
The assembly of individual two-dimensional materials into van der Waals heterostructures enables the construction of layered three-dimensional materials with desirable electronic a…
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…
