Exact theory of plasmon reflection and transmission in partially gated two-dimensional system
I. M. Moiseenko, D. A. Svintsov
We develop an exact theory of plasmon scattering at the boundary between gated and ungated regions of a two-dimensional electron system (2DES). Using the Wiener-Hopf technique, we…
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…
Plasmon resonance in a sub-THz graphene-based detector: theory and experiment
I. M. Moiseenko, E. Titova, M. Kashchenko +1
We present a combined experimental and theoretical study of photovoltage generation in a bilayer graphene (BLG) transistor structure exposed to subterahertz radiation. The device f…
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 drag in partly gated 2d electron system via highly confined screened plasmons
I. M. Moiseenko, D. A. Svintsov, Zh. A. Devizorova
Generation of photocurrent via photon drag effect enables very fast light detection with response time limited by momentum relaxation. At the same time, photon drag in bulk uniform…
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…
