Journal ArticleDOI

Wojciech Knap,C. Skierbiszewski,A. Zduniak,Elzbieta Litwin-Staszewska,D. Bertho,F. Kobbi,Jean-Louis Robert,G. E. Pikus,F. G. Pikus,S. V. Iordanskii,Vincent Mosser,Konstantinos Zekentes,Yu. B. Lyanda-Geller +12 more
TL;DR: Comparison of the experiment and the theory have allowed us to determine what mechanisms dominate the spin-relaxation in quantum wells and to improve the accuracy of determination of spin-splitting parameters in crystals and two-dimensional structures.
Journal ArticleDOI
Study of Transport, Phase, and Spin Relaxation Times of 2D Electrons by Means of Pressure
Wojciech Knap,A. Zduniak,A. Zduniak,L. H. Dmowski,L. H. Dmowski,Sylvie Contreras,Michel Dyakonov,Michel Dyakonov +7 more
TL;DR: In this article, magnetoconductivity experiments were carried out on pseudomorphic AlGaAs/InGaA/GaAs quantum wells in a wide range of magnetic fields (0.1 to 80 kG) for tuning the free electron density.
Journal ArticleDOI
Study of Quantum and Classical Scattering Times in Pseudomorphic AlGaAs/InGaAs/GaAs by Means of Pressure
L. H. Dmowski,L. H. Dmowski,A. Zduniak,A. Zduniak,Elzbieta Litwin-Staszewska,Sylvie Contreras,Wojciech Knap,Jean-Louis Robert +7 more
TL;DR: In this paper, two different persistent photoionization mechanisms induced by the light pulses, which have quite different effects on the two kinds of scattering times, have been investigated and it was shown that a modification of the spatial correlation of charges on remote donors in the barrier (by means of pressure and/or illumination by light pulses) affects the quantum lifetime much more than the transport scattering time.
Journal ArticleDOI
Universal Behaviour of Magnetoconductance due to Weak Localization in Two-Dimensional Systems - Example of GaInAs Quantum Wells
TL;DR: In this paper, the authors studied the magnetic field dependence of the conductivity in GalnAs quantum wells and developed a theoretical description that allows one to describe in a consistent way high and low field behaviour.
Journal ArticleDOI
Weak Antilocalization in Quantum Wells
Wojciech Knap,C. Skierbiszewski,Elzbieta Litwin-Staszewska,F. Kobbi,A. Zduniak,Jean-Louis Robert,G. E. Pikus,S. V. Iordanskii,Vincent Mosser,Konstantinos Zekentes +9 more
TL;DR: In this paper, it was shown that spin precession around the effective magnetic field direction is the main spin relaxation mechanism in degenerated 2D electron gas in semiconductors with no inversion symmetry.
