Spin-flip transitions in self-assembled quantum dots

Spin-flip transitions in self-assembled quantum dots

Detailed realistic calculations of the spin-flip time (T1) for an electron in a self-assembled quantum dot (SAQD) due to emission of an acoustic phonon, using only bulk properties with no fitting parameters, are presented. Ellipsoidal lens shaped InxGa1−xAs quantum dots, with electronic states calcu...

description Detailed realistic calculations of the spin-flip time (T1) for an electron in a self-assembled quantum dot (SAQD) due to emission of an acoustic phonon, using only bulk properties with no fitting parameters, are presented. Ellipsoidal lens shaped InxGa1−xAs quantum dots, with electronic states calculated using 8-band strain dependent k⋅p theory, are considered. The phonons are treated as bulk acoustic phonons coupled to the electron by both deformation potential and piezoelectric interactions. The dependence of T1 on the geometry of SAQD, on the applied external magnetic field and on the lattice temperature is highlighted. The theoretical results are close to the experimental measurements on the spin-flip times for a single electron in QD.
