Popis: We report on the observation of terahertz radiation induced ratchet effects in HgTe/HgCdTe-based quantum well (QWs) structures with a comb-like dual-grating-gate (DGG) structures. For investigations, we used various HgTe QWs with thickness of the 8.0, 7.0, and 6.3 nm, corresponding to parabolic dispersion with inverted band structure (8.0 and 7.0 nm) and linear dispersion (6.3 nm).
