Infrared resonance Raman of bilayer graphene: signatures of massive fermions and band structure on the 2D peak
Lorenzo Graziotto, Francesco Macheda, Tommaso Venanzi +14
Few-layer graphene possesses low-energy carriers which behave as massive fermions, exhibiting intriguing properties in both transport and light scattering experiments. Lowering the…
Probing enhanced electron-phonon coupling in graphene by infrared resonance Raman spectroscopy
Tommaso Venanzi, Lorenzo Graziotto, Francesco Macheda +16
We report on resonance Raman spectroscopy measurements with excitation photon energy down to 1.16 eV on graphene, to study how low-energy carriers interact with lattice vibrations.…
Intersubband transition engineering in the conduction band of asymmetric coupled Ge/SiGe quantum wells
Luca Persichetti, Michele Montanari, Chiara Ciano +9
: n-type Ge/SiGe asymmetric-coupled quantum wells represent the building block of a variety of nanoscale quantum devices, including recently proposed designs for a silicon-based TH…
Plasmonic superchiral lattice resonances in the mid-infrared
Francesco Mattioli, Giuseppe Mazzeo, Giovanna Longhi +14
Recent efforts in the field of surface-enhanced spectroscopies have focused on the paradigm of superchirality, entailing the engineering of the local electromagnetic fields to boos…
Room temperature operation of n-type Ge/SiGe terahertz quantum cascade lasers predicted by non-equilibrium Green's functions
T. Grange, D. Stark, G. Scalari +9
n-type Ge/SiGe terahertz quantum cascade laser are investigated using non-equilibrium Green's functions calculations. We compare the temperature dependence of the terahertz gain pr…
Fractal-like plasmonic self-similar material with a tailorable plasma frequency in the near-infrared
Denis Garoli, Eugenio Calandrini, Angelo Bozzola +4
In this work, we show that modulating the fractal dimension of nanoporous gold allows its effective dielectric response to be tailored over a wide spectral range of infrared wavele…
