Reporting Excellent Transverse Piezoelectric and Electro‐Optic Effects in Transparent Rhombohedral PMN‐PT Single Crystal by Engineered Domains

Adv. Mater. 2021, 33, 2103013 DOI: 10.1002/adma.202103013 1. In the rectangular coordinate system 2 of Figure 1 in the published article, the original coordinate axis Y2 [ 1 ¯ 01 $\bar{1}01$ ] is marked incorrectly, and is hereby corrected as Y2 [ 1 1 ¯ 0 $1\bar{1}0$ ]. [ 1 1 ¯ 0 $1\bar{1}0$ ] is orthogonal to X2 and Z2. Therefore, the article requires 23 modifications. In crystallography, the <101> direction is equivalent. The marks are used to distinguish the polarization direction from its vertical plane. Therefore, this correction does not have any impact on the core content and conclusions of the paper. All the corresponding corrections are summarized below: a) In the main text Line 11 of left column on page 2 (paragraph 3 of Section 1): The transparent direction is either the [110] or [ 1 1 ¯ 0 $1\bar{1}0$ ] direction, which is challenging to distinguish because these two crystallographic directions are equivalent. Line 4 of the right column on page 2 (paragraph 1 of Section 2.1) “As shown in Figure 1a, some samples were cut into rectangles with the X1, Y1, and Z1 axes along the [100], [010], and [001] directions, whereas the others were cut along the X2, Y2, and Z2 axes along the [001], [ 1 1 ¯ 0 $1\bar{1}0$ ], and [110] directions.” Line 10 of the left column on page 3 (paragraph 1 of Section 2.1): “These samples exhibit almost perfect transparency along the [110] and [001] directions and remain stable after poling during long-term storage; however, they depicted very poor transparency along the [ 1 1 ¯ 0 $1\bar{1}0$ ] direction.” Line 8 of the left column on page 6 (paragraph 3 of Section 2.2): “Because there exist merely 71° domain walls, the continuity of domain flipping will not be hindered, and some uncombined 71° domain walls are parallel to the ( 1 1 ¯ 0 $1\bar{1}0$ ) side distributed in the layers.” Line 16 of the left column on page 8 (paragraph 3 of Section 2.3): “Slightly tilting of the (001) cutting plane to the [110] direction has a little effect on the transparency. However, when it slightly tilts to the [ 1 1 ¯ 0 $1\bar{1}0$ ] direction, the incident light polarized along the [110] direction will be scattered, which will affect the light transmission.” Line 10 in the left column of the Experimental Section on page 10 (in the Sample Preparation subsection): “The crystals were oriented by X-ray diffraction (XRD) and cut along the X1, Y1, and Z1 axes along the [100], [010], and [001] directions (cut type 1), and with the X2, Y2, and Z2 axes along the [001], [ 1 1 ¯ 0 $1\bar{1}0$ ], and [110] directions (cut type 2).” Line 2 of the right column on page 10 in the Experimental Section (in the Dielectric and Piezoelectric Measurements subsection): “Using the LCR digital bridge (Tonghui, TH2827c), the d31 value of the [001] × [ 1 1 ¯ 0 $1\bar{1}0$ ] × [110] cut type crystal were determined by the resonance method according to the IEEE standard.” In addition, in the 2nd line of the caption of Figure 8 on page 8, “ 1 1 ¯ 0 $1\bar{1}0$ ]” is corrected as “[ 1 1 ¯ 0 $1\bar{1}0$ ]”. The opening bracket is missing in the published version: “b) The [ 1 ¯ 1 ¯ 1 $\bar{1}\bar{1}1$ ], [ 1 1 ¯ 1 $1\bar{1}1$ ], [111], and [ 1 ¯ 11 $\bar{1}11$ ] domains are illustrated in the schematics, which can form 71° or 109° domain walls.” b) Corrections are also made in the figures as shown below: In Figure 1a on page 2: In Figure 2a on page 3: In Figure 4a–d on page 5: In Figure 5a,b on page 5: In Figure 6a,d on page 6: In Figure 7a–d on page 7: 2. The abscissa in Figure 2b on page 3 is modified from nanometers to micrometers to be consistent with the formula.
