Electron spin-phonon relaxation in quantum dots
Brazilian journal of physics
We calculate the spin relaxation rates in parabolic quantum dots due to the phonon modulation of the spin-orbit interaction in presence of an external magnetic field. Both, deformation potential (DP) and piezoelectric (PE) electron-phonon couplings are included in the Pavlov-Firsov spin-phonon Hamiltonian. We demonstrate that the spin relaxation rates are particularly sensitive with the Landé g-factor, and that for InAs dots the DP can be necessarily considered in the spin relaxation analysis.doi:10.1590/s0103-97332004000400051 fatcat:pyba5pgg65cdpnvddq67mmff4a
