Quantum dots based on spin properties of semiconductor heterostructures
M. Valin-Rodriguez, A. Puente, L. Serra
The possibility of a novel type of semiconductor quantum dots obtained by spatially modulating the spin-orbit coupling intensity in III-V heterostructures is discussed. Using the e…
Spin splitting and precession in quantum dots with spin-orbit coupling: the role of spatial deformation
Manuel Valin-Rodriguez, Antonio Puente, Llorens Serra
Extending a previous work on spin precession in GaAs/AlGaAs quantum dots with spin-orbit coupling, we study the role of deformation in the external confinement. Small elliptical de…
Electron spin precession in semiconductor quantum wires with Rashba spin-orbit coupling
Manuel Valin-Rodriguez, Antonio Puente, Llorens Serra
The influence of the Rashba spin-orbit coupling on the electron spin dynamics is investigated for a ballistic semiconductor quantum wire with a finite width. We monitor the spin ev…
