Query: Spin transistor operation driven by the Rashba spin-orbit coupling in
  the gated nanowire   The theoretical description has been proposed for the operation of the spin
transistor in the gate-controlled InAs nanowire. The calculated current-voltage
characteristics show that the current flowing from the source (spin injector)
to the drain (spin detector) oscillates as a function of the gate voltage,
which results from the precession of the electron spin caused by the Rashba
spin-orbit interaction in the vicinity of the gate. We have studied two
operation modes of the spin transistor: (A) the ideal operation mode with the
full spin polarization of electrons in the contacts, the zero temperature, and
the single conduction channel corresponding to the lowest-energy subband of the
transverse motion and (B) the more realistic operation mode with the partial
spin polarization of the electrons in the contacts, the room temperature, and
the conduction via many transverse subbands taken into account. For mode (A)
the spin-polarized current can be switched on/off by the suitable tuning of the
gate voltage, for mode (B) the current also exhibits the pronounced
oscillations but with no-zero minimal values. The computational results
obtained for mode (B) have been compared with the recent experimental data and
a good agreement has been found.
