In the paper, we study electronic transport property through a quantum point contact with the saddle-point potential. Our numerical approach is based on the Green's function technique which is evaluated at the Hartree-Fork level. We reproduce relevant features of 0.7 structure when the strength of electron-electron interaction has changed. Besides, we calculate spin accumulation and noise factor at zero temperature. We deepen the understanding of the effect of strong correlation interaction on spin transport in nanometer semiconductor device.
