Terahertz optical activity near crystal field transitions of Tm3+ ions in magnetoelectric alumoborates
A. M. Kuzmenko, V. Yu. Ivanov, S. V. Garnov +5
Crystal field (CF) excitations in the ground multiplet of Tm ions were investigated using terahertz transmission spectra of magnetoelectric TmAl(BO) and…
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…
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…
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…
Universal transparency and fine band structure near the Dirac point in HgTe quantum wells
V. Dziom, A. Shuvaev, J. Gospodaric +6
Spin-orbit coupling in thin HgTe quantum wells results in a relativistic-like electron band structure, making it a versatile solid state platform to observe and control non-trivial…
