Figure 3. Switching dynamics between multiple states. (A) Polarization evolution as a function of external pulsed electric field; (B) Schematical illustration of all possible switching routes between the four stable states controlled by electric fields; (C) Two proposed approaches to obtaining all states from any initial state.
