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…
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…
Novel SuperLattice Plasmon Mode in a Grating of 2D Electron Strips
V. M. Muravev, K. R. Dzhikirba, A. A. Zabolotnykh +7
We investigate GaAs/AlGaAs heterostructure membranes with a metasurface made up of a grating of two-dimensional electron system (2DES) strips. Experiments have revealed a strong pl…
On the Nature of the Fundamental Plasma Excitation in a Plasmonic Crystal
A. R. Khisameeva, A. Shuvaev, A. A. Zabolotnykh +5
We report on the experimental study of the spectrum of plasma excitations in a plasmonic crystal fabricated from the two-dimensional electron system in an AlGaAs/GaAs semiconductor…
