Why a diffusing single-molecule can be detected in few minutes by a large capturing bioelectronic interface
Eleonora Macchia, Liberato De Caro, Fabrizio Torricelli +4
Single-molecule detection at a nanometric interface in a femtomolar solution, can take weeks as the encounter rate between the diffusing molecule to be detected and the transducing…
Tunable, grating-gated, graphene-on-polyimide terahertz modulators
Alessandra Di Gaspare, Eva A. A. Pogna, Luca Salemi +10
We present an electrically switchable graphene terahertz (THz) modulator with a tunable-by-design optical bandwidth and we exploit it to compensate the cavity dispersion of a quant…
Nanoscale displacement sensing based on nonlinear frequency mixing in quantum cascade lasers
F. P. Mezzapesa, L. L. Columbo, G. De Risi +4
We demonstrate a sensor scheme for nanoscale target displacement that relies on a single Quantum Cascade Laser (QCL) subject to optical feedback. The system combines the inherent s…
Comparative analysis of resonant phonon THz quantum cascade lasers
Christian Jirauschek, Giuseppe Scarpa, Paolo Lugli +2
We present a comparative analysis of a set of GaAs-based THz quantum cascade lasers, based on longitudinal-optical phonon scattering depopulation, by using an ensemble Monte Carlo…
