Query: Ferroelectric control of the giant Rashba spin orbit coupling in
  GeTe(111)/InP(111) superlattice   GeTe wins the renewed research interest due to its giant bulk Rashba spin
orbit coupling (SOC), and becomes the father of a new multifunctional material,
i.e., ferroelectric Rashba semiconductor. In the present work, we investigate
Rashba SOC at the interface of the ferroelectric semiconductor superlattice
GeTe(111)/InP(111) by using the first principles calculation. Contribution of
the interface electric field and the ferroelectric field to Rashba SOC is
revealed. A large modulation to Rashba SOC and a reversal of the spin
polarization is obtained by switching the ferroelectric polarization. Our
investigation about GeTe(111)/InP(111) superlattice is of great importance in
the application of ferroelectric Rashba semiconductor in the spin field effect
transistor.
