Velocity Control of 180° Domain Walls in Ferroelectric Thin Films by Electrode Modification
The velocity of individual 180° domain walls in thin ferroelectric films of PbZr0.1Ti0.9O3 is strongly dependent on the thickness of the top Pt electrode made by electron-beam induced deposition (EBID). We show that when the thickness is varied in the range
