Patent ID: 7235851

Claim:
A spin transistor, comprising: an emitter with a first resistance; a collector for providing a potential barrier, the collector being the only potential barrier of the spin transistor, wherein the collector includes at least one of a diode and a resistor, the diode includes at least one of a p-n junction diode, p-i-n diode, a Schottky-barrier diode, a planar-doped-barrier diode, a tunnel diode, a resonant-tunneling diode, a resonant-interband-tunneling diode, a single-barrier tunnel diode, a single-barrier an interband-tunneling diode, a real-space-transfer diode, a heterostructure hot-electron diode, a impact-ionization-avalanche transit-time diode, a barrier-injection transit-time diode, a p-i-n photodiode, a Schottky-barrier photodiode and an avalanche photodiode; and a base for coupling the emitter and the collector.
