Effect of an InP/In $_{0.53}$ Ga $_{0.47}$ As Interface on Spin-orbit Interaction in In $_{0.52}$ Al $_{0.48}$ As/In $_{0.53}$ Ga $_{0.47}$ As Heterostructures

Y. Lin, T. Koga, J. Nitta

We report the effect of the insertion of an InP/In $_{0.53}$ Ga $_{47}$ As Interface on Rashba spin-orbit interaction in In $_{0.52}$ Al $_{0.48}$ As/In $_{0.53}$ Ga $_{0.47}$ As quantum wells…

Competition between Spin-Orbit Interaction and Zeeman Coupling in Rashba 2DEGs

F. E. Meijer, A. F. Morpurgo, T. M. Klapwijk +2

We investigate systematically how the interplay between Rashba spin-orbit interaction and Zeeman coupling affects the electron transport and the spin dynamics in InGaAs-based 2D el…

Statistical significance of fine structure in the frequency spectrum of Aharonov-Bohm conductance oscillations

F. E. Meijer, A. F. Morpurgo, T. M. Klapwijk +2

We discuss a statistical analysis of Aharonov-Bohm conductance oscillations measured in a two-dimensional ring, in the presence of Rashba spin-orbit interaction. Measurements perfo…
