Electron magnetotransport in GaAs/AlGaAs superlattices with weak and strong inter-well coupling
L. Smrcka, N. A. Goncharuk, P. Svoboda +3
We report on magnetotransport measurements in two MBE-grown GaAs/AlGaAs superlattices formed by wide and narrow quantum wells and thin Si-doped barriers subject to tilted magnetic…
Electronic structure of unidirectional superlattices in crossed electric and magnetic fields and related terahertz oscillations
L. Smrcka, N. A. Goncharuk, M. Orlita +1
We have studied Bloch electrons in a perfect unidirectional superlattice subject to crossed electric and magnetic fields, where the magnetic field is oriented ``in-plane'', i.e. in…
Illumination-induced changes of the Fermi surface topology in three-dimensional superlattices
N. A. Goncharuk, L. Smrcka, P. Svoboda +4
The magnetoresistance of the MBE-grown GaAs/AlGaAs superlattice with Si-doped barriers has been measured in tilted magnetic fields in the as-grown state, and after brief illuminati…
