Abstract: The D'yakonov-Perel' spin relaxation process in the (001) InAs quantum well system is studied based on Monte Carlo (MC) simulation. The present space-resolved MC analysis demonstrates that the relaxation of spins oriented in any axes is totally suppressed with equal strength of Rashba and Dresselhaus effects, which is in marked contrast with the spin relaxation anisotropy reported previously in time-resolved analyses. Our calculation also shows a substantial contribution of the cubic term of the wave number vector in the Dresselhaus model onto the spatial spin distribution.
