Abstract
We investigate theoretically the D'yakonov-Perel' spin relaxation time by solving the eight-band Kane model and Poisson equation self-consistently. Our results show distinct behavior with the single-band model due to the anomalous spin-orbit interactions in narrow band-gap semiconductors, and agree well with the experiment values reported in recent experiment (K. L. Litvinenko, et al., New J. Phys. \textbf{8}, 49 (2006)). We find a strong resonant enhancement of the spin relaxation time appears for spin align along [] at a certain electron density at 4 K. This resonant peak is smeared out with increasing the temperature.
