Abstract
A spin injector for use in a microelectronic device such as a field effect transistor (FET) is disclosed. The spin injector includes an array of ferromagnetic elements disposed within a semiconductor. The ferromagnetic elements within the array are arranged and spaced with respect to one another in a close arrangement such that electrons or holes are spin-polarized when passing through. The spin injector may be located above or at least partially within a source region of the FET. A spin injector structure may also be located above or at least partially within the drain region of the FET. The spin injector includes a semiconductor material containing an array of ferromagnetic elements disposed in the semiconductor material, wherein adjacent ferromagnetic elements within the array are separated by a distance within the range between about 1 nm and 100 nm.
