Time resolved fullfield imaging of ferroelectric domains of KxNa1-xNbO3 thin films

This proposal is a continuation of HC-4354. We study the dynamics of phase transitions, in particular the transition from the ferroelectric monoclinic (Mc-) phase to the ferroelectric orthorhombic (c-) phase in Potassium Sodium Niobate K0.7Na0.3NbO3.
Instead of performing scanning imaging diffraction experiments as in previous beamtimes we plan to resort to time-resolved fullfield imaging. We expect a reduction of the measurement time from 10 hours per delay point to only 20 minutes.
