Av. Khaetskii et Yv. Nazarov, Spin-flip transitions between Zeeman sublevels in semiconductor quantum dots - art. no. 125316, PHYS REV B, 6412(12), 2001, pp. 5316
We have studied spin-flip transitions between Zeeman sublevels in GaAs elec
tron quantum dots. Several different mechanisms which originate from spin-o
rbit coupling are shown to be responsible for such processes. It is shown t
hat spin-lattice relaxation for the electron localized in a quantum dot is
much less effective than for the free electron. The spin-flip rates due to
several other mechanisms not related to the spin-orbit interaction are also
estimated.
