Hole spin relaxation in semiconductor quantum dots

Abstract

Hole spin relaxation time due to the hole-acoustic phonon scattering in GaAs\nquantum dots confined in quantum wells along (001) and (111) directions is\nstudied after the exact diagonalization of Luttinger Hamiltonian. Different\neffects such as strain, magnetic field, quantum dot diameter, quantum well\nwidth and the temperature on the spin relaxation time are investigated\nthoroughly. Many features which are quite different from the electron spin\nrelaxation in quantum dots and quantum wells are presented with the underlying\nphysics elaborated.\n
