Fig. 4: Ferroelectric domains change by heat and light.

From: Domain memory effect in the organic ferroics

Fig. 4

Consecutive images showing erasure and recurrence of stripe domains in SA-NPh-(S) thin-film via both thermal treatment and light irradiation. The red and blue regions indicate the two different polarization-oriented states of ferroelectric domains. Domain patterns for SA-NPh-(S) thin-film a at the initial state, b after heating to the Phase II and c cooling down to the room temperature, subsequently d after 365 nm UV light irradiation, and e after 488 visible light irradiation.
