We report anisotropic transport observed in unidirectional lateral superlattices (LSL) with period a = 92 nm, at high (6 ΒΏ N ΒΏ 1) Landau levels (LLs). Near the half-ΓΏlling of the LLs (up to ΓΏlling factor = 25 2 ), sharp peaks are observed in the resistance traces when current is along the grating t
We report the first far-infrared linear and non-linear (saturation) magneto absorption experiments of coupled subband-Landau level excitations in a series of modulation-doped double-coupled multiple quantum-well (MQW) structures. Non-linear spectroscopy is carried out with a free electron laser. A p
This study is concerned with a two-dimensional electron-hole system in a strong perpendicular magnetic field with special attention devoted to the influence of the virtual quantum transitions of interacting particles between the Landau levels. It is shown that virtual quantum transitions of two Coul
