【摘要】 研究了电子通过反对称双磁垒纳米结构的输运性质,计算了电子的透射几率和电导。通过与对称的双磁垒比较,反对称双磁垒纳米结构具有更强的波矢滤波的性质,但是透射几率和电导都大大地减小。更多还原

【Abstract】 We have investigated theoretically the transport properties of electrons in dissymmetric double-barrier magnetic nanostructures, and calculated the transmission probability and conductance of the electrons. Compared with the symmetry double magnetic-barriers, the dissymmetry double magnetic-barriers have stronger wave-vector-filtering feature. But both the transmission and conductance are drastically reduced for electrons tunneling through dissymmetric double-barrier magnetic nanostructures.更多还原
