Patent ID: 8487358

Claim:
A spin field effect logic device comprising: a channel including a magnetic material configured to selectively transmit spin-polarized electrons; a source on the channel; a gate electrode on the channel; a drain electrode configured to output electrons transmitted from the source; an output electrode configured to output electrons transmitted from the source; an input terminal connected to the gate electrode; and an output terminal connected to the output electrode, wherein the gate electrode is configured to control a magnetization state of the channel in order to selectively transmit electrons injected from the source into the channel, the channel is configured to selectively transmit the spin-polarized electrons which are spin-polarized in a first direction when the channel is in a first magnetization state, and the drain and the output electrode include a magnetic material, the drain magnetized in a second direction and the output electrode magnetized in the first direction, and wherein the logic device is configured such that when a potential of the input terminal is greater than or equal to a threshold voltage, the channel is in a second magnetization state and selectively transmits electrons which are spin-polarized in the second direction, and an output voltage of the output terminal is low, and when the input terminal is at a ground voltage, the output voltage of the output terminal is high.
