Figure 4
(a) Drawing of used CeB6(001) surface with image acquisition positions [red dots: this figure (b); gray dots: Figs. SM1 (0°) and SM2 (45°) of the supporting information]. (b) TEEM images of used CeB6 at representative positions along the 0° direction taken at 1000°C before and after 1500°C annealing. Grayscales of the images (shown by scale bars) are varied for different conditions in order to show the image contrast clearly. |
