Unconventional quantization of 2D plasmons in cavities formed by gate slots
Ilia Moiseenko, Zhanna Devizorova, Olga Polischuk +2
We demonstrate that the slot between parallel metal gates placed above two-dimensional electron system (2DES) forms a plasmonic cavity with unconventional mode quantization. The re…
Discovery of Slot Plasma Excitations in a AlGaN/GaN Plasmonic Crystal
A. R. Khisameeva, A. Shuvaev, I. M. Moiseenko +6
We experimentally investigate the terahertz spectrum of plasma excitations in a plasmonic crystal based on AlGaN/GaN two-dimensional electron system (2DES). While screened plasmon…
Electromagnetic diffraction and bidirectional plasmon launching in partially gated 2d systems
Ilia Moiseenko, Egor Nikulin, Dmitry Svintsov
Partially gated two-dimensional electron systems (2DES) represent the basic building block of prospective optoelectronic devices, including electromagnetic detectors and sources. A…
Exact theory of edge diffraction and launching of transverse electric plasmons at two-dimensional junctions
Dmitry Svintsov, Alexander Shabanov
An exact solution for electromagnetic wave diffraction at the junction of two-dimensional electron systems (2DES) is obtained and analyzed for electric field polarized along the ed…
Slow interband recombination promotes an anomalous thermoelectric response of the junctions
Aleksandr S. Petrov, Dmitry Svintsov
Thermoelectric effects in junctions are widely used for energy generation with thermal gradients, creation of compact Peltier refrigerators and, most recently, for sensitive…
