摘要： When a gate voltage VGS is applied, the Schottky barrier width due to the metallic spin band in the ferromagnetic source is decreased, and up-spin electrons from the metallic spin band are tunnel-injected into the channel region. However, down-spin electrons from the nonmagnetic contact (3b) are not injected because of the energy barrier due to semiconductive spin band of the ferromagnetic source (3a). That is, only up-spin electrons are injected into the channel layer from the ferromagnetic source (3a). If the ferromagnetic source (3a) and the ferromagnetic drain (5a) are parallel magnetized, up-spin electrons are conducted through the metallic spin band of the ferromagnetic drain to become the drain current. Contrarily, if the ferromagnetic source (3a) and the ferromagnetic drain (5a) are antiparallel magnetized, up-spin electrons cannot be conducted through the ferromagnetic drain (5a) because of the energy barrier Ec due to the semiconductive spin band in the ferromagnetic drain (5a). Thus, a high-performance high-degree of integration nonvolatile memory composed of MISFETs operating on the above operating principle can be fabricated.
摘要翻译：当施加栅极电压VGS时，由铁磁源中的金属自旋带引起的肖特基势垒宽度减小，并且来自金属自旋带的向上自旋电子被隧道注入到沟道区域中。然而，由于由于铁磁源（3a）的半导电自旋带而导致的能量势垒，因此来自非磁性接触（3b）的下旋电子不会被注入。也就是说，只有上自旋电子从铁磁源（3a）注入沟道层。如果铁磁源（3a）和铁磁性漏极（5a）被平行磁化，则上行电子通过铁磁性漏极的金属自旋带传导成漏极电流。相反，如果铁磁源（3a）和铁磁性漏极（5a）是反平行磁化的，则由于铁磁性漏极中的半导体自旋带导致的能量势垒Ec，上升自旋电子不能通过铁磁性漏极（5a）传导（5A）。因此，可以制造以上述工作原理工作的由MISFET组成的高性能高集成度非易失性存储器。

摘要： A MISFET the channel region of which is a ferromagnetic semiconductor has a feature that the drain current can be controlled by the gate voltage and a feature that the transfer conductance can be controlled by the relative directions of magnetization in the ferromagnetic channel region and the ferromagnetic source (or the ferromagnetic drain, or both the ferromagnetic source and ferromagnetic drain). As a result binary information can be stored in the form of the relative magnetization directions, and the relative magnetization directions are electrically detected. If the magnetism is controlled by the electric field effect of the channel region of a ferromagnetic semiconductor, the current needed to rewrite the information can be greatly reduced. Thus, the MISFET can constitute a high-performance non-volatile memory cell suited to high-density integration.
摘要翻译：其沟道区域是铁磁半导体的MISFET具有可以通过栅极电压来控制漏极电流的特征，并且具有可以通过铁磁通道区域和铁磁源中的相对磁化方向来控制转移电导的特征（或铁磁性漏极，或铁磁源和铁磁性漏极）。结果，可以以相对磁化方向的形式存储二进制信息，并且电检测相对磁化方向。如果磁性由铁磁半导体的沟道区域的电场效应控制，那么可以大大减少重写信息所需的电流。因此，MISFET可以构成适合于高密度集成的高性能非易失性存储单元。

摘要： A spin filtering device has: a spin filter (1) having an input region (3) for carrying an electron current, an output region (4) for carrying an electron current, and a three-dimensionally confined quantum region (2a) arranged to operate in the Coulomb blockade regime and separating the input and output regions (3 and 4) whereby electrons can only pass from the input region to the output region by tunnelling through the quantum region; and Zeeman splitting means (5) for causing Zeeman splitting in the spin filter, the quantum region (2a) and input and output regions (3 and 4) being formed such that the Zeeman splitting in the input and output regions (3 and 4) is less than the Fermi energy such that, in operation, the spin filter outputs a tunnelling current predominantly of one spin polarity. The direction of Zeeman splitting may be controlled to control the predominant spin polarity.
