Nonlinear Terahertz Resonances from Ballistic Electron Funnelling
Hue T. B. Do, Gregory K. Ngirmang, Wu Lin +1
We introduce a new mechanism for second-harmonic generation through geometrically rectifying-funneling-ballistic electrons in THz optical resonators. Our resonant rectifiers inhere…

Slow, Nanometer Light Confinement Observed in Atomically Thin TaS2
Hue T. B. Do, Meng Zhao, Pengfei Li +9
Extreme light confinement down to the atomic scale has been theoretically predicted for ultrathin, Ta-based transition metal dichalcogenides (TMDs). In this work, we experimentally…

Particle-In-Cell Simulations of Quantum Plasmas
Gregory K. Ngirmang, Hue T. B. Do, Guangxin Liu +2
Room-temperature metals and semi-metals which consist of a gas of bound electrons in a near-continuum band structure can be classified as cold quantum plasmas. This insight suggest…
