我们探索了如何通过操纵一组沉积在其异质结顶部表面的图图化栅极发出的边缘磁场来修改二维电子气体的传输特性。我们提出了一种多栅极器件，其电导敏感地依赖于其栅极的相对磁化，因此可以用作平面磁阻器件或作为存储结构。0 2005美国物理学会。
We explore how the transmission properties of a two-dimensional electron gas can be modified by manipulating the fringing magnetic fields that emanate from a set of patterned gates, deposited on the top surface of its heterojunction. We propose a multigate device whose conductance is shown to depend sensitively upon the relative magnetization of its gates, and which may therefore be of use as a planar magnetoresistance device, or as a memory structure. 0 2005 American Institute Of Physics.
