Tailored nano-electronics and photonics with two-dimensional materials at terahertz frequencies
Leonardo Viti, Miriam Serena Vitiello
The discovery of graphene and its fascinating capabilities have triggered an unprecedented interest in inorganic two-dimensional (2D) materials. Van der Waals (vdW) layered materia…
Quantum-dot single-electron transistor as thermoelectric quantum detectors at terahertz frequencies
Mahdi Asgari, Dominique Coquillat, Guido Menichetti +6
Low dimensional nano-systems are promising candidates for manipulating, controlling and capturing photons with large sensitivities and low-noise. If quantum engineered to tailor th…
Chip-scale terahertz frequency combs through integrated intersubband polariton bleaching
Francesco P. Mezzapesa, Leonardo Viti, Lianhe Li +5
Quantum cascade lasers (QCLs) represent a fascinating accomplishment of quantum engineering and enable the direct generation of terahertz (THz) frequency radiation from an electric…
Homogeneous quantum cascade lasers operating as Terahertz frequency combs over their entire operational regime
Alessandra Di Gaspare, Leonardo Viti, Harvey E. Beere +2
We report a homogeneous quantum cascade laser (QCL) emitting at Terahertz (THz) frequencies, with a total spectral emission of about 0.6 THz centered around 3.3 THz, a current dens…
Unveiling the detection dynamics of semiconductor nanowire photodetectors by terahertz near-field nanoscopy
Eva A. A. Pogna, Mahdi Asgari, Valentina Zannier +3
Semiconductor nanowire field-effect transistors represent a promising platform for the development of room-temperature (RT) terahertz (THz) frequency light detectors due to the str…
Thermoelectric graphene photodetectors with sub-nanosecond response times at Terahertz frequencies
Leonardo Viti, Alisson R. Cadore, Xinxin Yang +7
Ultrafast and sensitive (noise equivalent power <1 nWHz-1/2) light-detection in the Terahertz (THz) frequency range (0.1-10 THz) and at room-temperature is key for applications suc…
