Ebsd single crystal
WebThe EBSD method was used to probe the larger domains in the single crystal. The EBSD image shows the distribution of the orientations in the crystal and surrounding matrix, where the difference in colors inside the single crystal is attributed to the differently oriented ferroelectric domains. From the color-key inverse-pole figure, it can be ... WebThe sample was cut from a single crystal into a 12×3×3 mm 3 testing bar and polished to a high-quality metallographic finish using gradually decreasing diamond particle size in suspension, from 10 to 3 to 1 μm, …
