Inhomogeneous micro-strain in cylindrical semiconductor heterostructures and its influence on the adiabatic motion of electrons
B Jenichen, U Jahn, A Nikulin +3
We analyze fluctuation of the layer thicknesses and its influence on the strain state of (In,Ga)As/(Al,Ga)As micro-tubes containing quantum well structures. In those structures a c…
Electrical suppression of spin relaxation in GaAs(111)B Quantum Wells
A. Hernández-Mínguez, K. Biermann, R. Hey +1
Spin dephasing via the spin-orbit interaction (SOI) is a major mechanism limiting the electron spin lifetime in III-V zincblende quantum wells. The dephasing can be suppressed in G…
Electric control of spin transport in GaAs (111) quantum wells
A. Hernández-Mínguez, K. Biermann, R. Hey +1
We show by spatially and time-resolved photoluminescence that the application of an electric field transverse to the plane of an intrinsic GaAs (111) quantum well (QW) allows the t…
A microscopic model for the magnetic field driven breakdown of the dissipationless state in the integer and fractional quantum Hall effect
A. Poux, Z. R. Wasilewski, K. J. Friedland +5
Intra Landau level thermal activation, from localized states in the tail, to delocalized states above the mobility edge in the same Landau level, explains the (half width…
Nano-Ratchet sets free electrical power even without intentional excitation
H. Weidlich, V. Hortelano, W. T. Masselink +3
In theory ratchets enable energy harvesting by rectifying electrical fluctuations in conductors and semiconductors. Certain rectification effects in nanostructures have been demons…
Coherent transport and manipulation of spins in indirect exciton nanostructures
Adriano Violante, Rudolf Hey, Paulo Ventura Santos
We report on the coherent control and transport of indirect exciton (IX) spins in GaAs double quantum well (DQW) nanostructures. The spin dynamics was investigated by optically gen…
