Query: Ideal switching effect in periodic spin-orbit coupling structures   An ideal switching effect is discovered in a semiconductor nanowire with a
spatially-periodic Rashba structure. Bistable `ON' and `OFF' states can be
realized by tuning the gate voltage applied on the Rashba regions. The energy
range and position of `OFF' states can be manipulated effectively by varying
the strength of the spin-orbit coupling (SOC) and the unit length of the
periodic structure, respectively. The switching effect of the nanowire is found
to be tolerant of small random fluctuations of SOC strength in the periodic
structure. This ideal switching effect might be applicable in future spintronic
devices.
