Effects of spin imbalance on the electric-field driven quantum dissipationless spin current in $p$-doped Semiconductors

Liangbin Hu, Ju Gao, Shun-Qing Shen

It was proposed recently by Murakami et al. [Science \textbf{301}, 1348(2003)] that in a large class of $p$-doped semiconductors, an applied electric field can drive a quantum diss…
