Fig. 8From: The Growth of Polarization Domains in Ultrathin Ferroelectric Films Seeded by the Tip of an Atomic Force MicroscopeSimulated electric field applied by the AFM tip in 2, 10 and 40 nm films by COMSOL (point line), and the electric field due to the cone (Eq. 5) and the electric field expressed by Eq. 3 of previous works [10, 13, 14] (solid lines). The tip radius is 60 nm (tip \(\#\)1). (See Additional file 1.)Back to article page
