| Abstract: | We present a spin current generator based on a T-shaped double quantum dot (TDQD) molecule connected with two leads, and the coherent spin-flip effect is taken into account within the TDQD. The spin current from the right output terminal is obtained, more importantly, the properties of the spin current are investigated in detail, these results offer us a way to manipulate the spin current with the system parameters. |
