Description:
Author(s): Yanxia Xing, Zhong-liu Yang, Qing-feng Sun, and Jian Wang We report on the injection of quantized pure spin current into quantum conductors. In particular, we propose an on-demand single-spin source generated by periodically varying the gate voltages of two quantum dots that are connected to a two-dimensional topological insulator via tunneling barriers.
