Research paperExperimental CharacterizationTheoreticalNovel SuperLattice Plasmon Mode in a Grating of 2D Electron StripsV. M. Muraveva, K. R. Dzhikirbaa, A. A. Zabolotnykh, P. A. Gusikhina et al.2026·10.1103/vp8j-ws4g·arXiv:2508.12182AbstractWe 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 plasma resonance in the transmission of the metasurface. We have found that a collective effect from the superlattice, along with lateral screening between the strips, leads to the emergence of a new plasmon mode in the metasurface under study. Furthermore, we develop an analytical approach that accurately describes the behavior of the discovered superlattice plasmon mode, providing new insights into the fundamental physics of plasmonic metasurface systems.Read more
