Viti L, Riccardi E, Beere H, Ritchie D, Vitiello M
ACS Nano . 2023 Mar; 17(6):6103-6112. PMID: 36883532
The on-chip integration of two-dimensional nanomaterials, having exceptional optical, electrical, and thermal properties, with terahertz (THz) quantum cascade lasers (QCLs) has recently led to wide spectral tuning, nonlinear high-harmonic generation,...

Wang D, Krix Z, Sushkov O, Farrer I, Ritchie D, Hamilton A, et al.
Nano Lett . 2023 Feb; 23(5):1705-1710. PMID: 36790264
Imposing an external periodic electrostatic potential to the electrons confined in a quantum well makes it possible to engineer synthetic two-dimensional band structures, with electronic properties different from those in...

Di Gaspare A, Pistore V, Riccardi E, Pogna E, Beere H, Ritchie D, et al.
Adv Sci (Weinh) . 2023 Jan; 10(9):e2206824. PMID: 36707499
Mode locking, the self-starting synchronous oscillation of electromagnetic modes in a laser cavity, is the primary way to generate ultrashort light pulses. In random lasers, without a cavity, mode-locking, the...

Vianez P, Jin Y, Moreno M, Anirban A, Anthore A, Tan W, et al.
Sci Adv . 2022 Jun; 8(24):eabm2781. PMID: 35714181
An electron is usually considered to have only one form of kinetic energy, but could it have more, for its spin and charge, by exciting other electrons? In one dimension...

Michailow W, Spencer P, Almond N, Kindness S, Wallis R, Mitchell T, et al.
Sci Adv . 2022 Apr; 8(15):eabi8398. PMID: 35427162
Many mid- and far-infrared semiconductor photodetectors rely on a photonic response, when the photon energy is large enough to excite and extract electrons due to optical transitions. Toward the terahertz...
