THz carrier dynamics in $S r T i O_{3} / L a T i O_{3}$ interface two-dimensional electron gases

Ahana Bhattacharya, Andri Darmawan, Jeong Woo Han +10

A two-dimensional electron gas (2DEG) forms at the interface of complex oxides like $S r T i O_{3}$ (STO) and $L a T i O_{3}$ (LTO), despite each material having a low native conductivity,…

Extreme Terahertz Nonlinearity of AlGaN/GaN-based Grating-Gate Plasmonic Crystals

Pavlo Sai, Vadym V. Korotyeyev, Dmytro B. But +12

We present a novel approach to enhance THz nonlinearity by the resonant excitation of two-dimensional plasmons in grating-gate plasmonic crystals. Using a high-electric-field THz p…
