摘要：
We investigate the electron spin relaxation between Zeeman sublevels of fully three-dimensional quantum dots. By going beyond the usual two-dimensional description of Rashba and spin-orbit interactions (SOI), We provide a general overview of the effect of the quantum dot shape. It is shown that, in spherical quantum dots, the Dresselhaus SOI is severely suppressed, leading to slow relaxation rates and a strong (B-9) dependence on the magnetic field.
