Images for SEM Montage

Densely-pixelated SEM image was used to calculate the Ga coverage percentage and produce the panorama view over a 2 mm length scale in Figure 6e-f. The methods of this part are explained in supporting figures S14, S15, S16, S17, S18, and table S2. The methods are also explained in the method sections 4.12, 4.13, and 4.14.<br>

本研究采用高像素密度扫描电子显微镜（SEM）图像计算镓（Ga）覆盖率，并生成图6e-f中尺度为2毫米的全景视图。本部分的实验方法详见补充材料图S14、S15、S16、S17、S18及表S2，同时亦可参见方法章节4.12、4.13与4.14。
