Nanoscale Dynamics of Superdomain Boundaries in Single‐Crystal BaTiO₃ Lamellae

Accelerated domain switching speed in single-crystal LiNbO3 thin films

“…9,[14][15][16][17][18] This similarity evidences that the peeled-off thin films maintain the main feature of their bulk, identical to the freestanding BaTiO 3 platelets fabricated through ion thinning of single crystals. 21 currents. 12,13 With the increase in the field strength, the peak of the switching current becomes narrower and its position moves into the shorter time in Fig.…”

The Nature of Magnetoelectric Coupling in Pb(Zr,Ti)O3–Pb(Fe,Ta)O3

“…To enable our investigation, thin single crystal platelets, or lamellae, were cut from the interior of individual grains of PZTFT ceramic using focused ion beam (FIB) milling. As has been done in previous research, these lamellae were integrated into simple capacitor devices by placing them across an interelectrode gap (of the order of a few microns in thickness) between coplanar thin film platinum electrodes. The crystallographic orientation was determined by FIB‐cutting a second lamella, parallel to the first, from the same PZTFT grain, transferring onto a carbon‐coated 3 mm diameter grid and investigating using electron diffraction, in a 200 kV field emission transmission electron microscope.…”

Ferroelectric Domain Wall Injection

“…While ‘hot‐spots' have been seen to induce domain nucleation, it was expected that cold‐spots could significantly impede domain wall propagation. This expectation was tested by monitoring the motion of domain walls under an applied planar electric field using in‐situ PFM imaging in a KTP lamellar capacitor structure with two pairs of FIB‐milled triangular holes ( Figure ). The modeled electric field distribution for this pattern under an applied bias is shown in Figure a.…”
